1. A nurse is preparing to administer a scheduled dose of digoxin
0.25 mg PO to an adult client who has a historical diagnosis of
chronic heart failure. Before pulling the medication from the
automated dispensing cabinet, which physiological parameter
serves as the primary safety gate that the nurse must evaluate?
• The client's blood pressure in both arms while sitting.
• The client's apical pulse rate for one full minute.
• The client's fractional respiratory depth and rhythm.
• The client's immediate axillary temperature reading.
*Correct Answer Description: Digoxin is a cardiac glycoside with
negative chronotropic properties. The nurse must assess the
apical pulse for 1 full minute and withhold the dose if the heart
rate is below 60 bpm in adults to prevent severe bradycardia
[134].
2. A nurse is reviewing the laboratory results for a client who is
currently receiving a continuous intravenous infusion of
unfractionated heparin to treat a deep vein thrombosis (DVT).
Which laboratory parameter must the nurse evaluate closely to
titrate the dose safely and minimize the risk of internal
hemorrhage?
,• Prothrombin Time (PT)
• International Normalized Ratio (INR)
• Activated Partial Thromboplastin Time (aPTT)
• Erythrocyte Sedimentation Rate (ESR)
*Correct Answer Description: Unfractionated heparin efficacy
and safety margins are monitored using the aPTT. Prothrombin
time and INR are utilized to track oral warfarin therapy [5, 24].
3. A client with chronic kidney disease (CKD) is prescribed a regular
dose of epoetin alfa subcutaneously. During a follow-up outpatient
monitoring visit, the nurse evaluates the client's vital signs and
trends. Which adverse effect represents a major cardiovascular risk
associated with this medication?
• Profound orthostatic hypotension
• Accelerated systemic hypertension
• Severe bradycardia with QRS widening
• Acute respiratory depression
*Correct Answer Description: Epoetin alfa stimulates red blood
cell production, increasing blood viscosity and volume. This can
lead to rapid elevations in blood pressure and increases the risk of
hypertensive encephalopathy and stroke [103].
4. A nurse is reinforcing discharge education for a client who has a
new prescription for oral ferrous sulfate tablets to treat iron-
deficiency anemia. To optimize intestinal absorption and minimize
common gastrointestinal side effects, which instruction should the
nurse include?
• "Take the iron pill with a large glass of whole milk right before
bed."
• "Mix the medication with a hot cup of black tea to mask the
metallic flavor."
• "Take the medication with a glass of orange juice and
increase your daily fiber intake."
• "Take an over-the-counter calcium carbonate antacid right
alongside the iron."
*Correct Answer Description: Vitamin C (found in orange juice)
, significantly enhances the absorption of non-heme iron. Iron
supplements frequently cause constipation; increasing dietary
fiber and fluid intake helps mitigate this effect [131].
5. A client who has been diagnosed with an acute flare-up of systemic
lupus erythematosus (SLE) is prescribed a high dose of oral
prednisone. When delivering long-term safety education, which
adverse effect must the nurse instruct the client to report
immediately due to the risk of an immune-masking effect?
• Mild weight gain and a rounding of the facial contour.
• A low-grade fever or any subtle signs of a localized
infection.
• The appearance of fine stretch marks across the abdomen.
• An increased appetite during the initial week of treatment.
*Correct Answer Description: Prednisone is a potent
corticosteroid that suppresses immune system function. This
increases susceptibility to infections and suppresses the normal
inflammatory response, potentially masking classic symptoms
like a high fever [85].
6. A nurse is preparing to administer an intramuscular (IM) injection
of a water-soluble antibiotic to a well-developed 9-month-old
infant. Which anatomical site represents the safest, evidence-based
selection for this specific age bracket?
• The deltoid muscle of the upper arm.
• The dorsogluteal muscle site.
• The vastus lateralis muscle of the anterolateral thigh.
• The ventrogluteal muscle site.
*Correct Answer Description: The vastus lateralis muscle is the
preferred and safest site for IM injections in infants under 12
months old because it has the largest muscle mass and lacks
major nerves or large blood vessels [99, 181].
7. A nurse is evaluating a client's medication list and notes a new
prescription for sublingual nitroglycerin tablets to manage stable
angina. Which storage instruction must the nurse emphasize to
ensure the chemical compound remains potent over time?
, • "Keep the tablets loose in a clear plastic medicine planner on the
kitchen windowsill."
• "Transfer the pills to a large, clear plastic bottle so you can easily
verify the volume."
• "Store the tablets exclusively in their original dark glass
bottle, capped tightly, away from heat."
• "Place the prescription bottle inside the freezer compartment of
your refrigerator."
*Correct Answer Description: Nitroglycerin degrades rapidly
when exposed to light, heat, or ambient moisture. It must always
be kept inside its original amber or dark glass container with the
cap secured tightly [90].
8. A client with history of severe alcoholism is admitted to the
medical-surgical unit displaying confusion, horizontal nystagmus,
and ataxia. The nurse anticipates an immediate prescription for
the intravenous administration of which vitamin to prevent
permanent neurological deterioration? [1]
• Vitamin B12 (Cyanocobalamin)
• Vitamin B1 (Thiamine)
• Vitamin C (Ascorbic Acid)
• Vitamin K (Phytonadione)
*Correct Answer Description: These symptoms are classic
indicators of Wernicke’s encephalopathy, a neurological
emergency caused by a severe deficiency of thiamine (Vitamin
B1), common in chronic alcohol use disorder [91].
9. A nurse is caring for a client who is receiving a continuous
intravenous infusion of regular insulin for the treatment of diabetic
ketoacidosis (DKA). The client's hourly blood glucose level has
successfully dropped from 400 mg/dL to 240 mg/dL. Which
intravenous fluid adjustment should the nurse anticipate next?
• Discontinue the insulin infusion immediately and convert the line
to a saline lock.
• Increase the rate of the regular insulin infusion to clear remaining
glucose faster.
