,Question 1
A nurse in the emergency department is assessing a client who presents with a severe
headache, a stiff neck, and a high fever. Which of the following isolation precautions
should the nurse implement immediately?
A) Airborne precautions
B) Contact precautions
C) Droplet precautions
D) Protective environment
Correct Answer: C) Droplet precautions
Rationale: The client's clinical triad of headache, nuchal rigidity (stiff neck), and fever is
highly suggestive of acute bacterial meningitis. Neisseria meningitidis is transmitted
through large-particle droplets from the respiratory tract. Droplet precautions require a
private room and a surgical mask worn by anyone entering within 3 feet of the client to
prevent transmission.
Question 2
A nurse is preparing to administer packed red blood cells (PRBCs) to a client who has
severe symptomatic anemia. Which of the following intravenous fluids is the only
solution compatible with blood products?
A) 0.45% Sodium Chloride
B) 5% Dextrose in Water (D5W)
C) Lactated Ringer's
D) 0.9% Sodium Chloride
Correct Answer: D) 0.9% Sodium Chloride
Rationale: 0.9% Sodium Chloride (Normal Saline) is an isotonic fluid that is completely
compatible with blood products. Other fluids cause hemolysis or clotting of the blood
sample within the IV line. Hypotonic solutions like 0.45% NaCl cause red blood cells to
swell and burst, while dextrose-containing solutions like D5W cause RBC aggregation.
Question 3
A nurse is assessing a client who is 4 hours postoperative following a subtotal
thyroidectomy. Which of the following signs should the nurse prioritize to monitor for
acute hypocalcemia?
A) Positive Chvostek's sign
B) Hypoactive deep tendon reflexes
C) Flaccid muscle tone
D) Prolonged PR interval
Correct Answer: A) Positive Chvostek's sign
Rationale: Subtotal thyroidectomy carries an intrinsic risk of accidental removal or
damage to the parathyroid glands, leading to acute hypoparathyroidism and
hypocalcemia. A positive Chvostek's sign (facial twitching elicited by tapping the facial
,nerve anterior to the ear) is a classic indicator of neuromuscular irritability due to low
calcium levels.
Question 4
A nurse is caring for a client with Type 1 Diabetes Mellitus who is unresponsive,
diaphoretic, and has a blood glucose level of 42 mg/dL. The client does not have
established intravenous access. Which medication should the nurse administer?
A) Regular Insulin 10 units subcutaneously
B) Glucagon 1 mg intramuscularly
C) 50% Dextrose 50 mL intravenously
D) Metformin 500 mg orally
Correct Answer: B) Glucagon 1 mg intramuscularly
Rationale: For an unconscious or unresponsive client experiencing severe
hypoglycemia who lacks functional intravenous access, the immediate treatment of
choice is Glucagon administered intramuscularly or subcutaneously. This stimulates
hepatic glycogenolysis to rapidly raise blood sugar. Regular insulin would worsen the
hypoglycemia, and oral agents cannot be given due to aspiration risks.
Question 5
A nurse is caring for a client who is taking Warfarin for chronic atrial fibrillation. The
nurse notes the client's International Normalized Ratio (INR) is 5.2. Which of the
following medications should the nurse anticipate administering?
A) Protamine sulfate
B) Vitamin K
C) Enoxaparin
D) Heparin sodium
Correct Answer: B) Vitamin K
Rationale: The therapeutic INR range for a client taking Warfarin for atrial fibrillation is
typically 2.0 to 3.0. An INR of 5.2 signifies a critical level of over-anticoagulation and a
high risk for spontaneous bleeding. Vitamin K is the specific pharmacological antidote
used to reverse the anticoagulant effects of Warfarin.
Question 6
A nurse is reviewing the lab results of a client with Chronic Kidney Disease (CKD). The
client's serum potassium level is 6.4 mEq/L. Which of the following prescription
modifications or medications should the nurse prioritize?
A) Spironolactone PO daily
B) Potassium chloride IV infusion
C) Sodium polystyrene sulfonate or Sodium zirconium cyclosilicate PO
D) Intravenous 0.9% Sodium Chloride bolus
Correct Answer: C) Sodium polystyrene sulfonate or Sodium zirconium
cyclosilicate PO
, Rationale: A serum potassium level of 6.4 mEq/L represents severe hyperkalemia
(normal range: 3.5 to 5.0 mEq/L), which can cause lethal cardiac dysrhythmias.
Potassium binders like sodium polystyrene sulfonate or sodium zirconium cyclosilicate
facilitate the excretion of excess potassium through the gastrointestinal tract to safely
lower serum levels.
Question 7
A nurse is preparing to care for a client who has a chest tube connected to a water-seal
drainage system. The nurse notes constant, vigorous bubbling in the water-seal
chamber. How should the nurse interpret this finding?
A) The chest tube is functioning normally.
B) The client's lung has fully re-expanded.
C) There is an air leak present in the drainage system.
D) The suction pressure setting is too low.
Correct Answer: C) There is an air leak present in the drainage system.
Rationale: Intermittent bubbling in the water-seal chamber is normal during expiration or
coughing, but constant, continuous bubbling indicates an air leak within the closed
drainage system or at the insertion site. The nurse must check all connections from the
client to the collection device to locate and secure the source of the leak.
Question 8
A nurse is evaluating a client who has advanced liver cirrhosis. Which of the following
laboratory values is directly responsible for the development of hepatic
encephalopathy?
A) Elevated serum Bilirubin
B) Decreased serum Albumin
C) Elevated serum Ammonia
D) Prolonged Prothrombin Time (PT)
Correct Answer: C) Elevated serum Ammonia
Rationale: In advanced cirrhosis, the failing liver cannot convert ammonia (a byproduct
of protein metabolism) into urea for renal excretion. Accumulated systemic ammonia
crosses the blood-brain barrier, exerting direct neurotoxic effects that cause the
cognitive deficits, confusion, altered mental status, and asterixis characteristic of hepatic
encephalopathy.
Question 9
A nurse is preparing to administer Digoxin 0.125 mg PO to a client with heart failure.
Which of the following actions must the nurse perform immediately prior to drug
administration?
A) Assess the client's radial pulse for a full 30 seconds.
B) Auscultate the client's apical pulse for 1 full minute.
C) Measure the client's blood pressure in a supine position.
D) Review the client's baseline serum calcium level.
