When educating a patient about taking iron tablets, which of the following instructions should the nurse provide?
Take the tablet with a glass of milk to enhance absorption.
Crush the tablet and mix it with yogurt for easier swallowing.
Take the tablet with a full glass of water to prevent constipation
Avoid taking the tablet with antacids or calcium supplements.
The Correct Answer is D
A. Milk contains calcium, which binds to iron and reduces its absorption, so iron tablets should not be taken with milk.
B. Crushing the tablet may be appropriate for some formulations, but mixing with yogurt or other dairy can interfere with absorption; the nurse should instruct clients to follow manufacturer instructions.
C. Taking iron with water does not prevent constipation; iron commonly causes constipation regardless of fluid intake, although adequate hydration can help manage it.
D. Antacids and calcium supplements can bind to iron and significantly reduce its absorption, so clients should be instructed to take iron at least 2 hours apart from these substances to ensure effectiveness.

Correct Answer is C
Explanation
A. An oxygen saturation of 95% is within normal limits and does not require withholding furosemide.
B. A serum sodium level of 140 mEq/L is normal; furosemide can lower sodium, but this value alone does not necessitate holding the medication.
C. A blood pressure of 80/40 mm Hg is significantly low (hypotension). Furosemide is a potent diuretic that can further lower blood pressure and reduce perfusion to vital organs, so the nurse should withhold the medication and notify the healthcare provider.
D. A serum potassium level of 4.8 mEq/L is within the normal range (3.5–5.0 mEq/L); monitoring is important because furosemide can cause hypokalemia, but this level does not require withholding the drug.
Correct Answer is A
Explanation
A. Hydralazine is an antihypertensive that relaxes blood vessels and lowers blood pressure. Frequent monitoring is important to ensure effectiveness and prevent hypotension, especially when starting therapy or adjusting the dose.
B. Clients are generally encouraged to maintain adequate fluid intake unless otherwise restricted; fluid restriction is not a standard precaution with hydralazine.
C. Grapefruit juice does not have a known interaction with hydralazine; this instruction is unnecessary.
D. Clients should not skip doses based on current blood pressure readings without consulting their healthcare provider, as this can lead to unstable blood pressure control.Top of FormBottom of Form
