Rationale: Constipation is a common side effect of iron supplements such as ferrous sulfate. Iron can cause constipation by slowing down the movement of the digestive system and hardening the stool. Patients should be advised to increase their fluid intake, dietary fiber, and physical activity to help alleviate this side effect.

Correct Answer: C

Rationale: Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Instructing the client to change positions slowly can help prevent this adverse effect. It is important for the client to consume foods rich in potassium to prevent hypokalemia. Taking furosemide in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.

Correct Answer: C

Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration.

Correct Answer: C

Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk.

Correct Answer: A

Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the HCP to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects.
