Full Question & Rationale Repository
Showing all 10 practice questions with expert explanatory rationales.
The client with varicella will most likely have an order for which category of medication?
Expert Explanatory Rationale
Correct Answer: Antivirals
Varicella (chickenpox) is a viral infection, and antivirals like acyclovir are commonly prescribed to reduce severity and duration.
A client with chronic obstructive pulmonary disease (COPD) is admitted to the respiratory unit. Which physician prescription should the nurse question?
Expert Explanatory Rationale
Correct Answer: O₂ at 5 L/min by nasal cannula
High-flow oxygen (5 L/min) can suppress the hypoxic drive in COPD clients, risking CO₂ retention. Low-flow oxygen (1-2 L/min) is safer and should be questioned.
A client with diabetes visits the prenatal clinic at 28 weeks gestation. Which statement is true regarding insulin needs during pregnancy?
Expert Explanatory Rationale
Correct Answer: Fetal development depends on adequate insulin regulation.
Adequate insulin regulation is critical for fetal development in diabetic pregnancies.
The nurse is caring for a client with documented severe allergies to latex. Which item on the client's meal tray should the nurse remove?
Expert Explanatory Rationale
Correct Answer: a banana
Bananas can cause a cross-reaction in latex-allergic clients due to shared proteins (latex-fruit syndrome). Other items are safe.
The nurse is caring for the client following a thyroidectomy when suddenly the client becomes nonresponsive and pale, with a BP of 60 systolic. The nurse's initial action should be to:
Expert Explanatory Rationale
Correct Answer: Increase the infusion of normal saline
Increasing normal saline infusion addresses hypovolemic shock, likely due to post-thyroidectomy hemorrhage, as the priority action.
A client with pulmonary edema is ordered IV hydrocortisone (Solu-Cortef) 40 mg b.i.d. Which laboratory value would the nurse expect to see as a result of this therapy?
Expert Explanatory Rationale
Correct Answer: elevated glucose
Hydrocortisone, a corticosteroid, increases blood glucose by promoting gluconeogenesis. Magnesium levels are not primarily affected.
A client with heart failure has a left ventricular ejection fraction of 38%. When educating the client about managing the condition, which of the following advice should the nurse include? Select all that apply.
Expert Explanatory Rationale
Correct Answer:
Rest periods (A), avoiding strenuous activities (B), and stopping smoking (D) manage heart failure. All exercise (C) is not stopped; moderate activity is encouraged. Alcohol should be minimal, not 2-3 drinks (E).
The physician has ordered an infusion of Osmitrol (mannitol) for a client with increased intracranial pressure. Which finding indicates the direct effectiveness of the drug?
Expert Explanatory Rationale
Correct Answer: Increased urinary output
Mannitol is an osmotic diuretic that reduces intracranial pressure by increasing urinary output, drawing fluid out of the brain tissue.
The nurse is taking the blood pressure of the obese client. If the blood pressure cuff is too small, the results will be:
Expert Explanatory Rationale
Correct Answer: A false elevation
A blood pressure cuff that is too small will result in a false elevation of the blood pressure reading due to increased pressure on the arm.
A labor and delivery nurse is caring for a client in active labor. The fetal monitor shows late decelerations. The nurse should first
Expert Explanatory Rationale
Correct Answer: place the client in left lateral recumbent position.
Late decelerations indicate uteroplacental insufficiency. The left lateral position improves placental perfusion, addressing the immediate cause.
