Question 1 of 5
A 27-year-old man with HIV disease and hepatitis B is hospitalized for treatment of his hepatitis B. He has begun on intravenous treatment with interferon. After administration, he develops fever, chills, and myalgias. Physical examination reveals that the lungs are clear to auscultation bilaterally. What is the most likely explanation for this reaction?
Correct Answer: A
Rationale: Interferon for hepatitis B commonly causes fever, chills, and myalgias as an expected adverse event . Drug toxicity implies overdose. Pneumonias (C, D, E) lack lung findings. This flu-like reaction is typical, resolving with continued use.
Question 2 of 5
During diuretic therapy, the nurse monitors the fluid and electrolyte status of the patient. Which assessment findings are symptoms of hyponatremia? (Select all that apply.)
Correct Answer: B
Rationale: Lethargy is A common symptom of hyponatremia, which is an electrolyte imbalance characterized by low sodium levels in The blood. This can lead to neurological symptoms such as confusion, weakness, and lethargy.
Question 3 of 5
The nurse teaches a class about medication used during pregnancy to pregnant women. The nurse determines that additional instruction is required when a class participant makes which response?
Correct Answer: A
Rationale: Drugs harm fetuses across trimesters-first (organogenesis) is critical, but later effects (e.g., growth) occur, so this needs correction. Avoiding OTC drugs is wise-many risk harm. Teratogens cause death or defects, true. Breast milk transfers drugs, also true. First-trimester-only harm misstates risk, requiring reteaching.
Question 4 of 5
Modest improvement in the memory of patients with Alzheimer's disease may occur with drugs that increase transmission at which of the following receptors?
Correct Answer: B
Rationale: Alzheimer's disease features cholinergic neuron loss, impairing memory via reduced acetylcholine signaling in the hippocampus and cortex. Drugs like acetylcholinesterase inhibitors (e.g., donepezil) boost cholinergic transmission by preventing acetylcholine breakdown, modestly improving memory and cognition in early stages. Adrenergic enhancement (e.g., via norepinephrine) affects arousal, not memory directly. Dopaminergic drugs treat Parkinson's, not Alzheimer's cognitive deficits. GABAergic drugs (e.g., benzodiazepines) inhibit cognition, worsening memory. Serotonergic agents target mood, not memory. The cholinergic deficit is a hallmark of Alzheimer's pathology, and augmenting this system remains a primary therapeutic strategy, validated by clinical outcomes.
Question 5 of 5
The home care nurse is providing teaching for a 59-year-old patient taking a nonselective beta-blocker. The nurse teaches the patient the importance of notifying the prescribing physician when what occurs related to this medication?
Correct Answer: B
Rationale: Bronchospasm, cough, rhinitis, and bronchial obstruction are related to loss of bronchodilation of the respiratory tract and vasodilation of mucous membrane vessels so a sudden onset of a cough or difficulty breathing should be immediately reported to the health care provider. Other options may need to be reported but not in relation to the nonselective beta-blocking medication. The nurse should educate the patient about potential adverse effects and the importance of timely reporting.
