1. A nurse is reviewing the cause of gout with a group of nurses. Which of the following statements should the
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


nurse make?
bh bh




A. "Uric acid levels drop and calcium forms precipitate."
bh bh bh bh bh bh bh




Rationale: W ith gout, clients have hyperuricemia, rather than a reduction in uric acid.
bh bh bh bh bh bh bh bh bh bh bh bh




B. "Tophi form in the kidneys and they impair the excretion of uric acid."
bh bh bh bh bh bh bh bh bh bh bh bh




Rationale: Tophi, or deposits in tissues near a joint, develop in chronic, late-stage gout. They are not part
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


of the primary disease process. bh bh bh bh bh




C. "The intra-articular deposition of urate crystals causes inflammation."
bh bh bh bh bh bh bh




Rationale: Gout, or gouty arthritis, develops when urate crystals deposit in joints and tissues and cause
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


inflammation and pain. bh bh bh




D. "Articular cartilage thins, leading to splitting and fragmentation."
bh bh bh bh bh bh bh




Rationale: Gout does not thin and fragment cartilage.
bh bh bh bh bh bh bh




2. A nurse is teaching a group of clients about osteoarthritis. Which of the following recommendations should the
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


nurse include in the teaching?
bh bh bh bh bh




A. Use Echinacea to manage joint pain.
bh bh bh bh bh




Rationale: The nurse may include the use of complementary and alternative therapies in the teaching.
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


However, Echinacea is used for the treatment of the common cold, not osteoarthritis. bh bh bh bh bh bh bh bh bh bh bh bh


Alternative therapies that are used for osteoarthritis include glucosamine, chondroitin, and
bh bh bh bh bh bh bh bh bh bh bh


topical capsaicin. bh bh




B. Apply ice to the joint before exercising.
bh bh bh bh bh bh




Rationale: The nurse should recommend that the clients begin exercising immediately following
bh bh bh bh bh bh bh bh bh bh bh


the application of heat. This reduces pain and improves mobility, allowing for
bh bh bh bh bh bh bh bh bh bh bh bh


increased range-of-motion during exercises. Cold application may be applied
bh bh bh bh bh bh bh bh bh


following exercise to decrease discomfort and inflammation.
bh bh bh bh bh bh bh




C. Maintain a recommended body weight. bh bh bh bh




Rationale: Obesity is a risk factor for the development of osteoarthritis. Maintenance of an ideal weight
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


is one way a client can prevent added wear and tear on joints and promote overall joint
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


health. bh




D. Reduce the amount of purine in the diet.
bh bh bh bh bh bh bh




Rationale: The nurse should recognize that limiting purine in the diet, which is often found in organ
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


meats, is recommended for clients who have gout.
bh bh bh bh bh bh bh bh




3. A nurse is caring for a client who has had a myocardial infarction. Upon his first visit to cardiac rehabilitation,
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh

bh bh bh bh bh bh bh bh bh bh bh




A. "Cardiac rehabilitation cannot undo the damage to your heart but it can help you get back to your
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


previous level of activity safely."
bh bh bh bh bh




Rationale: With this response, the nurse uses the therapeutic communication technique of presenting
bh bh bh bh bh bh bh bh bh bh bh bh


reality by indicating her perception of the situation for the client.
bh bh bh bh bh bh bh bh bh bh bh




B. "It’s not unusual to feel that way at first, but once you learn the routine, you’ll enjoy it."
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh




Rationale: W ith this response, the nurse illustrates the nontherapeutic communication technique of giving
bh bh bh bh bh bh bh bh bh bh bh bh


reassurance, thus discouraging the client from further communication.
bh bh bh bh bh bh bh bh




C. "Exercise is good for you and good for your heart."
bh bh bh bh bh bh bh bh bh




Rationale: W ith this response, the nurse illustrates the nontherapeutic communication techniques of
bh bh bh bh bh bh bh bh bh bh bh


disagreeing and giving advice. bh bh bh bh




D. "Your doctor is the expert here, and I’m sure he would only recommend what is best for you."
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh




Rationale: W ith this response, the nurse illustrates the nontherapeutic communication technique of
bh bh bh bh bh bh bh bh bh bh bh


defending. bh




4. A nurse is caring for a client who has heart failure and a potassium level of 2.4 mEq/L. The nurse should
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


identify which of the following medications as the cause of the client’s low potassium level?
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh




A. Furosemide

Rationale: Furosemide is a loop (high-ceiling) diuretic that inhibits the reabsorption of sodium and
bh bh bh bh bh bh bh bh bh bh bh bh bh


chloride and results in diuresis, which decreases potassium through excretion in the distal
bh bh bh bh bh bh bh bh bh bh bh bh bh


nephrons. bh


Hypokalemia is an adverse effect of furosemide. bh bh bh bh bh bh




B. Nitroglycerin
Rationale: A potassium level of 2.4 mEq/L is not an adverse effect of nitroglycerin. Nitroglycerin is a
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


vasodilator medication to treat angina.
bh bh bh bh bh




C. Metoprolol
Rationale: A potassium level of 2.4 mEq/L is not an adverse effect of metoprolol. Metoprolol
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


is a beta-blocker that slows the heart rate and improves contractility of the heart
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


muscle. bh




D. Spironolactone
Rationale: Spironolactone is a potassium-sparing diuretic medication; therefore, hyperkalemia is an
bh bh bh bh bh bh bh bh bh bh


adverse effect of this medication. bh bh bh bh bh




5. A nurse is caring for a client who is postoperative following an open reduction internal fixation (ORIF) of a
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


femur fracture. Which of the following parameters should the nurse include in the evaluation of the neurovascular
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


status of the client's affected extremity? (Select all that apply.)

A+
A. Color
B. Temperature

C. Ecchymosis

D. Skin integrity
bh




E. Sensation
Rationale: Color is correct. Clients who have sustained trauma to an extremity, such as a fracture,
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


are at increased risk for neurovascular compromise. The nurse should check the color of
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


the client's affected extremity as part of this assessment. The nurse should identify pallor
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


or cyanosis of the extremity as an indication of peripheral neurovascular dysfunction and
bh bh bh bh bh bh bh bh bh bh bh bh bh


should notify the provider.Temperature is correct. Clients who have sustained trauma to an
bh bh bh bh bh bh bh bh bh bh bh bh bh


extremity, such as a fracture, are at increased risk for neurovascular compromise. The
bh bh bh bh bh bh bh bh bh bh bh bh bh


nurse should monitor the temperature of the extremity as a part of this assessment and
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


identify skin that is cool or cold to the touch as having decreased perfusion to the tissues
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


of the extremity, which is an indication of peripheral neurovascular dysfunction. The nurse
bh bh bh bh bh bh bh bh bh bh bh bh bh


should report skin that is cool to the touch to the provider.Ecchymosis is incorrect.
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


Ecchymosis, or bruising, is an expected finding with leg injuries and is not a component of
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


a neurovascular check.Skin integrity is incorrect. While the nurse should assess the incision
bh bh bh bh bh bh bh bh bh bh bh bh bh


of a client who is postoperative following an open reduction and internal fixation of the
bh bh bh bh bh bh bh bh bh bh b h bh bh bh bh


femur, it is not a component of a neurovascular check.Sensation is correct. Clients who
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


have sustained trauma to an extremity, such as a fracture, are at increased risk for
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


neurovascular compromise. The nurse should assess the client's extremity for numbness or
bh bh bh bh bh bh bh bh bh bh bh bh


tingling. The nurse should recognize diminished pain or paresthesia as an indication of
bh bh bh bh bh bh bh bh bh bh bh bh bh


damage to the nerves or peripheral neurovascular dysfunction and should report it to the
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


provider. bh




6. A nurse is monitoring a client following a thoracentesis. The nurse should identify which of the following
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


manifestations as a complication and contact the provider immediately?
bh bh bh bh bh bh bh bh bh




A. Serosanguineous drainage from the puncture site
bh bh bh bh bh




Rationale: A small amount of serosanguineous drainage at the puncture site is expected after a
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


thoracentesis.
bh




B. Discomfort at the puncture site
bh bh bh bh




Rationale: Mild discomfort at the puncture site is expected after a thoracentesis.
bh bh bh bh bh bh bh bh bh bh bh




C. Increased heart rate
bh bh




Rationale: Clients are at risk for developing pulmonary edema or cardiovascular distress due mediastinal
bh bh bh bh bh bh bh bh bh bh bh bh bh


content shift after the aspiration of a large amount of fluid from the client's pleural space.
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


Therefore, the client may experience an increase in heart and respiratory rate, along with
bh bh bh bh bh bh bh bh bh bh bh bh bh


coughing with blood-tinged frothy sputum, and tightness in the chest. These findings require
bh bh bh bh bh bh bh bh bh bh bh bh bh


notification of the provider immediately.
bh bh bh bh bh




D. Decreased temperature
bh




Rationale: Infection is possible after any invasive procedure; however, it takes time to develop and
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


increases the body temperature.

7. A nurse is caring for a client who has a history of exposure to TB and symptoms of night sweats and
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


hemoptysis. Which of the following tests should the nurse realize is the most reliable to confirm the
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


diagnosis of active pulmonary TB?
bh bh bh bh bh




A. Chest x-ray bh




Rationale: A chest x-ray may be helpful for detecting old or new lesions that are large enough to be
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


visualized. However, the client who has an HIV infection may have a normal x-ray or show
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


infiltrates which would be expected in the client who has pneumonia.
bh bh bh bh bh bh bh bh bh bh bh




B. Sputum culture for acid-fast bacillus
bh bh bh bh




Rationale: Although the Mantoux (skin test) and the chest x-ray may be useful screening tools for TB,
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


the presence of acid-fast bacillus noted in the client's sputum, secretions, or tissues is the
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


only method that can actually confirm the diagnosis.
bh bh bh bh bh bh bh bh




C. Sputum smear bh




Rationale: A sputum smear is able to detect the presence of mycobacterium, but it does not distinguish
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


between mycobacterium tuberculosis and other strains of mycobacterium.
bh bh bh bh bh bh bh bh




D. Mantoux test bh




Rationale: The Mantoux skin test is an effective screening tool, but it is unable to distinguish between
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


an active case of TB and a client who has been, at some time in the past, exposed to
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


TB. The results are also variable, depending upon the skill of the nurse administrating and
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


reading the test. bh bh bh




8. A nurse in a medical clinic is providing teaching to an older adult client who has osteoarthritis that is affecting her
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


knees. Which of the following client statements indicates an understanding of the teaching?
bh bh bh bh bh bh bh bh bh bh bh bh bh




A. "I can use either heat or ice to help relieve the discomfort."
bh bh bh bh bh bh bh bh bh bh bh




Rationale: The nurse should reinforce that different treatment modalities, such as heat or cold therapy,
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


can be tried to determine which one is more effective for the client. Heat application can
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


help with muscle relaxation in the area around the affected joint. The application of cold
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


numbs nerve endings and decreases joint inflammation.
bh bh bh bh bh bh bh




B. "Ibuprofen is the first step in medication therapy for osteoarthritis."
bh bh bh bh bh bh bh bh bh




Rationale: The nurse should instruct the client that the primary medication of choice for the treatment of
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


osteoarthritis is acetaminophen. NSAIDS, such as celecoxib and ibuprofen, might be tried if
bh bh bh bh bh bh bh bh bh bh bh bh bh


acetaminophen does not control discomfort.
bh bh bh bh bh




C. "I should limit physical activity to prevent further injury."
bh bh bh bh bh bh bh bh




Rationale: The nurse should encourage the client to include aerobic exercise and lower extremity strength
bh bh bh bh bh bh bh bh bh bh bh bh bh bh


training into her daily regimen. These activities have been shown to slow the progression of
bh bh bh bh bh bh bh bh bh bh bh bh bh bh bh


osteoarthritis and relieve the manifestations of the disorder.
bh bh bh bh bh bh bh bh




D. "I will elevate my legs by placing two pillows under my knees when I go to bed."
