,A 68-year-old patient with a history of chronic heart failure is prescribed Digoxin (Lanoxin). The
patient reports experiencing nausea, vomiting, and visual disturbances described as yellow halos
around lights. The nurse recognizes these signs as indicative of Digoxin toxicity. Which of the following
is the priority intervention the nurse should anticipate?
A) Administering an antiemetic to manage the nausea and vomiting.
B) Withholding the next dose of Digoxin and obtaining a serum Digoxin level.
C) Encouraging the patient to increase fluid intake to flush the medication.
D) Applying a transcutaneous pacemaker due to the risk of asystole.
Correct Answer: B) Withholding the next dose of Digoxin and obtaining a serum Digoxin level.
Explanation / Rationale:
The patient is presenting with classic symptoms of Digoxin toxicity: gastrointestinal symptoms
(nausea, vomiting) and visual changes (yellow/green halos). The immediate priority is to prevent
further accumulation of the drug by withholding the next scheduled dose. Obtaining a serum Digoxin
level is essential to confirm the diagnosis and guide further treatment, such as the administration of
Digoxin Immune Fab (Digibind) if toxicity is severe.
A 55-year-old female patient with rheumatoid arthritis is prescribed Prednisone, a corticosteroid, for
long-term management of inflammation. The nurse provides education regarding the potential side
effects of glucocorticoid therapy. Which instruction is most critical for the nurse to include to prevent
a life-threatening complication?
A) "Take the medication on an empty stomach to enhance absorption."
B) "You may notice some weight gain and a rounded face; this is expected."
C) "Do not stop taking this medication abruptly; it must be tapered slowly."
D) "Limit your intake of green leafy vegetables to prevent interactions."
Correct Answer: C) "Do not stop taking this medication abruptly; it must be tapered slowly."
,Explanation / Rationale:
Abrupt cessation of long-term corticosteroid therapy can lead to acute adrenal insufficiency
(addisonian crisis). This occurs because exogenous steroids suppress the hypothalamic-pituitary-
adrenal (HPA) axis, reducing the natural production of cortisol. A sudden withdrawal leaves the body
unable to respond to stress, which can be fatal. Tapering allows the adrenal glands to recover and
resume normal cortisol production.
A student nurse is preparing to administer intravenous (IV) Vancomycin to a patient with a methicillin-
resistant Staphylococcus aureus (MRSA) infection. The instructor questions the student on the
rationale for infusing this medication over at least 60 minutes. What is the primary reason for this
administration guideline?
A) Vancomycin is a vesicant and rapid infusion causes tissue necrosis.
B) Rapid infusion of Vancomycin is associated with "Red Man Syndrome."
C) Vancomycin is unstable in solution and must be infused quickly to maintain potency.
D) Slow infusion is required to prevent severe hypotension associated with the medication's
antihypertensive effects.
Correct Answer: B) Rapid infusion of Vancomycin is associated with "Red Man Syndrome."
Explanation / Rationale:
"Red Man Syndrome" is a hypersensitivity reaction characterized by flushing, rash, pruritus, and
hypotension on the face, neck, and upper torso. It is caused by the direct degranulation of mast cells
and subsequent histamine release, not by an IgE-mediated mechanism. Infusing Vancomycin over at
least 60 minutes (or 2 hours for higher doses) significantly reduces the risk of this reaction.
A patient with atrial fibrillation is currently taking Warfarin (Coumadin) to prevent stroke formation.
The patient presents to the emergency department with a significant nosebleed that has persisted for
30 minutes despite pressure. The patient's International Normalized Ratio (INR) is 7.5. Which
medication should the nurse prepare to administer immediately?
A) Protamine sulfate.
B) Vitamin E.
C) Phytonadione (Vitamin K).
D) Aminocaproic acid.
, Correct Answer: C) Phytonadione (Vitamin K).
Explanation / Rationale:
Warfarin acts by inhibiting the synthesis of Vitamin K-dependent clotting factors (II, VII, IX, X). An INR
of 7.5 is significantly elevated (therapeutic range is usually 2.0–3.5 for atrial fibrillation) and places
the patient at high risk for spontaneous hemorrhage. Vitamin K is the specific antidote for Warfarin
toxicity. It reverses the anticoagulant effect by allowing the liver to resume synthesis of clotting
factors.
A 24-year-old female patient is prescribed Phenelzine, a Monoamine Oxidase Inhibitor (MAOI), for the
treatment of depression. During the dietary teaching session, which food item must the nurse strictly
instruct the patient to avoid to prevent a hypertensive crisis?
A) Aged cheese and red wine.
B) Leafy green vegetables.
C) Grapefruit juice.
D) Coffee and caffeinated sodas.
Correct Answer: A) Aged cheese and red wine.
Explanation / Rationale:
MAOIs inhibit the enzyme monoamine oxidase, which is responsible for breaking down tyramine in the
body. When a patient taking an MAOI consumes foods high in tyramine (such as aged cheeses, cured
meats, tap beers, and red wines), tyramine accumulates. This causes a massive release of
norepinephrine, leading to a hypertensive crisis characterized by severe headache, palpitations, neck
stiffness, and potentially stroke or death.
