Question 1 e




A nurse is assessing a client who has Raynaud's Phenomenon. Which of the following
e e e e e e e e e e e e e




e findings should the nurse expect?
e e e e




A) Cyanosis of the fingers and toes
e e e e e




B) Ulcerations on the fingertips e e e




C) Blanching of the fingers and toes e e e e e




D) Swelling and redness of the fingers and toes
e e e e e e e




Answer: C) Blanching of the fingers and toes
e e e e e e e




Rationale: Raynaud's phenomenon is characterized by vasospasm of the small arteries
e e e e e e e e e e




and arterioles in response to cold or stress. The classic triphasic color change is: white
e e e e e e e e e e e e e e e

,(blanching/pallor) from vasoconstriction, then blue (cyanosis) from deoxygenated blood,
e e e e e e e e




e followed by red (rubor) during rewarming. Blanching is the initial and most characteristic
e e e e e e e e e e e e




e finding. Ulcerations can occur in severe cases but are not the primary expected finding.
e e e e e e e e e e e e e




Swelling and redness are not typical of Raynaud's.
e e e e e e e e




Question 2 e




A nurse is caring for a client who had a cerebrovascular accident and is experiencing
e e e e e e e e e e e e e e




e expressive aphasia. Which of the following actions should the nurse take to assist the
e e e e e e e e e e e e e




e client to communicate their needs to health care providers?
e e e e e e e e




A) Apply suction for 10 seconds
e e e e




B) Provide written materials e e




C) Use flashcards with pictures
e e e




D) Massage uterus and expel clots e e e e




Answer: C) Use flashcards with pictures
e e e e e




Rationale: Expressive aphasia (Broca's aphasia) affects the ability to produce speech,
e e e e e e e e e e




e though comprehension is often intact. Flashcards with pictures allow the client to point
e e e e e e e e e e e e




e to what they need, facilitating communication. Written materials are less helpful because
e e e e e e e e e e e




e the client has difficulty expressing themselves in writing as well. Suctioning and uterine
e e e e e e e e e e e e




e massage are unrelated interventions.
e e e




Question 3 e




A nurse is providing teaching to a client about taking valproic acid. Which of the
e e e e e e e e e e e e e e




e following laboratory tests should the nurse instruct the client to have monitored
e e e e e e e e e e e




regularly?
e




A) Blood triglyceride levels e e




B) Serum electrolytes e




C) Serum liver enzyme levels e e e




D) Urine culture and sensitivity
e e e

, Answer: C) Serum liver enzyme levels
e e e e e




Rationale: Valproic acid (Depakote) is an anticonvulsant and mood stabilizer that carries a
e e e e e e e e e e e e




e black box warning for hepatotoxicity. Liver enzymes (AST, ALT) must be monitored
e e e e e e e e e e e




regularly to detect early liver damage. Pancreatitis is also a risk, but liver toxicity is the
e e e e e e e e e e e e e e e e




e primary concern requiring routine monitoring.
e e e e




Question 4 e




A nurse in an emergency department is caring for a client who is at 9 weeks gestation
e e e e e e e e e e e e e e e e




e and reports nausea and vomiting for the past 2 days with findings of dehydration.
e e e e e e e e e e e e e




Which of the following findings should the nurse expect?
e e e e e e e e




A) Increased serum potassium e e




B) Increased urine specific gravity e e e




C) Increased urine ketones e e




D) Increased serum sodium e e




Answer: B) Increased urine specific gravity
e e e e e




Rationale: Dehydration causes the kidneys to conserve water, resulting in
e e e e e e e e e




e concentrated urine with increased specific gravity (>1.030). Serum potassium is
e e e e e e e e e




e typically decreased in dehydration due to GI losses from vomiting. Urine ketones may
e e e e e e e e e e e e




e be present but are a sign of starvation, not a direct indicator of dehydration. Serum
e e e e e e e e e e e e e e




e sodium can be variable depending on the type of dehydration (hypertonic vs.
e e e e e e e e e e e




e isotonic).




Question 5 e




Complete the following sentence: The nurse should be most concerned about the
e e e e e e e e e e e




e client's e due to their risk for e e e e e .

A) Lung sounds; pneumoniae e




B) Blood glucose; diabetes e e




C) Heart rate; bradycardia e e
