Rationale style: Clinical evidence-based, "why right" + "why wrong" + high-yield concept.
1: A nurse is preparing to administer digoxin to a client with heart failure. Which assessment
finding requires the nurse to hold the medication and notify the healthcare provider?
Correct Answer: Apical pulse of 52 beats per minute.
1. Digoxin increases myocardial contractility but decreases heart rate (negative chronotrope). An
apical pulse below 60 bpm (adult) indicates bradycardia; digoxin is withheld to prevent worsening
bradycardia or heart block.
2. Evidence-based practice: Before each digoxin dose, assess apical pulse for 1 full minute. Withhold
if pulse <60 bpm in adults and notify provider, unless parameters specify otherwise.
3. Common distractors (e.g., serum potassium 3.8 mEq/L) are within normal range (3.5–5.0) and do
not require immediate withholding, though low potassium increases toxicity risk.
2: A nurse is caring for a client who reports severe pain 8/10 after abdominal surgery. Which
action should the nurse take first?
Correct Answer: Administer prescribed PRN analgesic.
1. Pain management is a priority for comfort, physiological stability, and preventing complications such
as splinting, atelectasis, or delayed ambulation. The nurse must address acute severe pain promptly.
2. Clinical guideline: For moderate to severe pain (≥7/10), pharmacologic intervention should be
prioritized. Non-pharmacologic measures (repositioning, distraction) are adjuncts, not first-line for
severe pain.
3. Waiting 30 minutes or calling the provider first is unnecessary delay; the nurse should use standing
PRN orders to treat pain unless contraindications exist.
3: Which clinical manifestation is most indicative of anaphylactic shock?
Correct Answer: Stridor and diffuse urticaria.
1. Stridor reflects laryngeal edema and airway obstruction; urticaria is an IgE-mediated histamine
release. Together they indicate anaphylaxis requiring immediate epinephrine.
2. Anaphylaxis involves rapidly progressive bronchospasm, hypotension, angioedema, and skin
reactions. Stridor suggests impending respiratory failure.
3. Orthostatic hypotension alone is nonspecific (occurs in hypovolemia). Wheezing can be asthma-
related; stridor is a more specific upper airway emergency sign in anaphylaxis.
, 4: A client with type 1 diabetes mellitus has a blood glucose of 45 mg/dL and is lethargic but
able to swallow. What is the nurse's priority intervention?
Correct Answer: Give 15 g of rapid-acting carbohydrate (e.g., 4 oz orange juice or 3
glucose tablets).
1. Hypoglycemia (<70 mg/dL) with altered mental status but intact swallow requires fast-acting oral
glucose (15-15 rule). This raises glucose rapidly to prevent neuroglycopenia.
2. Evidence: American Diabetes Association recommends 15 g carbs, recheck in 15 minutes. The
patient is lethargic but can swallow safely; IV dextrose or glucagon is unnecessary if oral intake
possible.
3. Holding all oral intake delays treatment and can worsen hypoglycemia. Administering insulin would
be catastrophic, further lowering glucose.
5: A nurse is providing discharge teaching to a client prescribed warfarin. Which statement
by the client indicates understanding?
Correct Answer: "I will avoid eating large amounts of spinach and kale."
1. Warfarin is a vitamin K antagonist; green leafy vegetables (spinach, kale, broccoli) are high in
vitamin K and can reduce INR, increasing thrombosis risk.
2. The key is consistency, not avoidance, but for understanding, the statement shows awareness that
vitamin K interferes. Taking aspirin with warfarin increases bleeding risk; "I'll take ibuprofen for
headaches" is dangerous due to GI bleeding potentiation.
3. Getting INR checked monthly is appropriate but the question focuses on dietary interaction. Best
indicator of understanding is recognizing the high-vitamin K food effect.
6: A nurse is assessing a client who is 2 hours post-cardiac catheterization via femoral
artery. Which finding requires immediate action?
Correct Answer: Expanding hematoma at the insertion site and absent pedal pulse on
the affected leg.
1. Expanding hematoma suggests active bleeding or retroperitoneal bleeding, and absent pedal pulse
indicates arterial occlusion or severe compression. This is limb-threatening.
2. Post-catheterization complications include hemorrhage, pseudoaneurysm, or thrombosis.
Immediate action: apply firm pressure, notify provider, prepare for vascular assessment.
3. Small amount of drainage or mild bruising is common. Pain at 3/10 without neurovascular changes
requires monitoring but is not emergent.
7: A nurse is planning care for a client with major depression. Which intervention is most
appropriate to address the priority nursing diagnosis of risk for self-directed violence?
Correct Answer: Initiate one-to-one observation and remove environmental hazards.
1. Safety is the highest priority in acute depression with suicidal ideation. One-to-one observation
(constant visual monitoring) prevents self-harm. Removing hazards includes cords, sharps,
medications.
2. Evidence-based suicide precautions: direct supervision, therapeutic environment, and no-harm
contracts are adjuncts but not substitutes for observation.
3. Encouraging group activity or restricting visitors does not directly mitigate immediate self-harm risk.
Behavioral activation is longer-term but not crisis oriented.
