Question 1 of 5
A client is prescribed an intranasal corticosteroid. What should the nurse include in client education about this drug?
Correct Answer: D
Rationale: Intranasal corticosteroids cause burning and nosebleeds . They're preventive (choice B wrong), dosing is fixed (choice C wrong). D educates on side effects, making it key.
Question 2 of 5
The following drugs may be administered transcutaneously to produce their systemic therapeutic effect:
Correct Answer: A
Rationale: GTN patches deliver the drug transdermally, bypassing first-pass metabolism and providing systemic therapeutic action.
Question 3 of 5
The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:
Correct Answer: A
Rationale: Chemotherapeutic DNA alkylating agents, such as nitrogen mustards, work by forming covalent bonds between alkyl groups on the drug and DNA strands. This cross-linking interferes with DNA replication and transcription, ultimately leading to cell death. This mechanism of action makes the alkylating agents effective in targeting rapidly dividing cancer cells.
Question 4 of 5
When counseling a male patient about the possible adverse effects of antihypertensive drugs, the nurse will discuss which potential problem?
Correct Answer: A
Rationale: One potential adverse effect of antihypertensive drugs, particularly beta-blockers and diuretics, is impotence. Antihypertensive medications can affect sexual function in males by causing erectile dysfunction or impotence due to their mechanism of action on blood vessels and circulation. It is important for the nurse to inform the patient about this possible side effect so that appropriate management strategies or alternative treatment options can be discussed. Impotence can have a significant impact on a patient's quality of life and adherence to medication, so open communication and education are essential in managing this issue.
Question 5 of 5
The nurse will monitor a patient for signs and symptoms of hyperkalemia if the patient is taking which of these diuretics?
Correct Answer: D
Rationale: Spironolactone is a potassium-sparing diuretic that works by promoting potassium retention in the body. Therefore, patients taking spironolactone are at a higher risk of developing hyperkalemia, which is an elevated level of potassium in the blood. Hyperkalemia can lead to serious complications such as cardiac arrhythmias, muscle weakness, and even cardiac arrest. It is important for the nurse to monitor patients on spironolactone for signs and symptoms of hyperkalemia, such as weakness, numbness, tingling, or an irregular heartbeat. Other diuretics like hydrochlorothiazide (A), furosemide (B), and acetazolamide (C) do not typically cause hyperkalemia as they work to decrease potassium levels in the body.
