A nurse is providing teaching to a client who has hypertension and a new prescription for captopril. Which of the following instructions should the nurse provide?
Expect to gain weight while taking this medication.
Do not use salt substitutes while taking this medication.
Count your pulse rate before taking the medication.
Take the medication with food.
The Correct Answer is B
Choice A reason: Expecting to gain weight while taking this medication is not a correct instruction, as it may discourage the client from adhering to the treatment and may worsen the hypertension. Captopril is an angiotensin-converting enzyme (ACE) inhibitor that lowers the blood pressure by preventing the formation of angiotensin II, a potent vasoconstrictor. Captopril does not cause significant weight gain, but it may cause fluid retention or edema in some cases. The nurse should advise the client to monitor the weight daily and report any sudden or excessive increase to the provider.
Choice B reason: Not using salt substitutes while taking this medication is a correct instruction, as it may prevent the risk of hyperkalemia, a potentially life-threatening condition. Captopril may increase the potassium level in the blood by reducing the secretion of aldosterone, a hormone that regulates the sodium and potassium balance. Salt substitutes may contain potassium chloride, which may further elevate the potassium level. The nurse should advise the client to avoid salt substitutes and high-potassium foods, such as bananas, oranges, or tomatoes, and to have regular blood tests to check the electrolyte levels.
Choice C reason: Counting the pulse rate before taking the medication is not a necessary instruction, as it may not reflect the effect of the medication on the blood pressure. Captopril does not affect the heart rate significantly, but it may lower the blood pressure too much, especially in the first few weeks of treatment or after a dose increase. This may cause hypotension, dizziness, or fainting. The nurse should advise the client to monitor the blood pressure regularly and report any symptoms of hypotension to the provider.
Choice D reason: Taking the medication with food is not a correct instruction, as it may reduce the absorption and effectiveness of the medication. Captopril should be taken on an empty stomach, at least one hour before or two hours after a meal, to ensure optimal bioavailability. The nurse should advise the client to take the medication at the same time every day and to avoid skipping or doubling the doses.

Correct Answer is B
Explanation
Choice A reason: Distended neck veins is not a manifestation of acute hemolytic reaction, but it may indicate fluid overload, which is another possible complication of blood transfusion. Fluid overload may occur when the blood volume or rate of infusion exceeds the client's circulatory capacity. Fluid overload may manifest as dyspnea, crackles, edema, hypertension, or tachycardia.
Choice B reason: Client report of low back pain is a manifestation of acute hemolytic reaction, which is a life-threatening condition that occurs when the donor blood is incompatible with the recipient's blood. Acute hemolytic reaction may occur within minutes or hours of the transfusion and may cause the destruction of the transfused red blood cells. Acute hemolytic reaction may manifest as fever, chills, low back pain, hemoglobinuria, hypotension, or shock.
Choice C reason: A productive cough is not a manifestation of acute hemolytic reaction, but it may indicate a respiratory infection, which is a potential risk of blood transfusion. Blood transfusion may transmit infectious agents, such as bacteria, viruses, or parasites, from the donor to the recipient. A productive cough may also be a sign of pulmonary edema, which may result from fluid overload or transfusion-related acute lung injury (TRALI).
Choice D reason: Client report of tinnitus is not a manifestation of acute hemolytic reaction, but it may indicate ototoxicity, which is a possible adverse effect of some medications, such as aminoglycosides, loop diuretics, or salicylates. Ototoxicity may damage the inner ear or the auditory nerve and cause hearing loss, tinnitus, or vertigo. The nurse should assess the client's medication history and monitor the client's hearing function.
Correct Answer is B
Explanation
Choice A reason: This is incorrect because dextrose 5% in 0.45% sodium chloride is a hypotonic solution that can cause hemolysis of the RBCs. It can also cause fluid shifts from the intravascular to the intracellular space, leading to edema and hypotension.
Choice B reason: This is correct because 0.9% sodium chloride is a isotonic solution that is compatible with blood products. It does not cause hemolysis or fluid shifts and maintains the osmotic pressure of the blood.
Choice C reason: This is incorrect because lactated Ringer's solution is a isotonic solution that contains electrolytes, such as potassium, calcium, and lactate, that can interfere with the blood products. It can also cause metabolic alkalosis due to the conversion of lactate to bicarbonate.
Choice D reason: This is incorrect because dextrose 5% in water is a hypotonic solution that can cause hemolysis of the RBCs. It can also cause fluid shifts from the intravascular to the intracellular space, leading to edema and hypotension.
