Question 1 of 5
A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client? Which information is most important for the nurse to provide this client?
Correct Answer: D
Rationale: Isotretinoin is highly teratogenic, posing severe risks of fetal abnormalities. Discontinuing the medication at least one month before conception ensures it is cleared from the body, preventing harm to the fetus.
Question 2 of 5
A peak and trough level was obtained from a client receiving an aminoglycoside IV every 8 hours. Which finding presents the highest risk for the client and should be reported immediately to the healthcare provider? Which finding presents the highest risk for the client and should be reported immediately to the healthcare provider?
Correct Answer: C
Rationale: Increased peak and trough levels of aminoglycosides indicate potential toxicity, risking nephrotoxicity (from high peaks) and ototoxicity (from high troughs). Immediate reporting to the provider prevents serious harm.
Question 3 of 5
A client is receiving miotics for the treatment of open-angle glaucoma. The nurse determines that a priority nursing problem is a 'Risk for injury' and this is based on which etiology? Which etiology is the basis for the 'Risk for injury' nursing problem?
Correct Answer: B
Rationale: Miotics constrict the pupil, reducing light entry and impairing night vision, which increases the risk of injury in low-light conditions. This etiology directly supports the 'Risk for injury' nursing problem.
Question 4 of 5
A client is scheduled for a spiral computed tomography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client’s history requires follow up by the nurse? Which information in the client’s history requires follow up by the nurse?
Correct Answer: B
Rationale: Metformin can increase the risk of lactic acidosis when combined with iodinated contrast media, especially if renal function is compromised. Follow-up is needed to consider temporarily discontinuing metformin before and after the CT scan to prevent this serious complication.
Question 5 of 5
A client with multiple sclerosis starts a new prescription, baclofen, to control muscle spasticity. Three days later, the client calls the clinic nurse and reports feeling fatigued and dizzy. Which instruction should the nurse provide? Which instruction should the nurse provide?
Correct Answer: D
Rationale: Baclofen can cause dizziness and fatigue, increasing the risk of falls or accidents. Advising the client to avoid hazardous activities like driving until symptoms subside enhances safety while the side effects are assessed.
