A nurse is caring for a client who is to receive a unit of packed RBCs. The nurse should prime the blood administration tubing using which of the following IV solutions?
Dextrose 5% in 0.45% sodium chloride
0.9% sodium chloride
Lactated Ringer's solution
Dextrose 5% in water
The Correct Answer is B
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.

Correct Answer is C
Explanation
Choice A reason: This is not a problem for a client who has hypertension and a new prescription for metoprolol, as metoprolol is a beta-blocker that can reduce the workload of the heart and improve the symptoms of heart failure.
Choice B reason: This is not a problem for a client who has hypertension and a new prescription for metoprolol, as metoprolol does not have any significant interactions with antibiotics or other medications used to treat pneumonia.
Choice C reason: This is a problem for a client who has hypertension and a new prescription for metoprolol, as tadalafil is a phosphodiesterase-5 inhibitor that can lower the blood pressure and cause hypotension when taken with metoprolol. The nurse should investigate further and notify the provider of the potential interaction.
Choice D reason: This is not a problem for a client who has hypertension and a new prescription for metoprolol, as metoprolol does not affect the blood glucose levels or the management of diabetes.
Correct Answer is D
Explanation
Choice A reason: Reducing intake of potassium-rich foods is not necessary for clients taking hydrochlorothiazide, as this medication can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Clients may need to increase their intake of potassium-rich foods or take potassium supplements to prevent hypokalemia.
Choice B reason: Avoiding grapefruit juice is not necessary for clients taking hydrochlorothiazide, as this medication does not interact with grapefruit juice. Grapefruit juice can affect the metabolism of some other medications, such as statins, calcium channel blockers, and cyclosporine, by inhibiting the enzyme CYP3A4 in the liver.
Choice C reason: Taking this medication before bedtime is not advisable for clients taking hydrochlorothiazide, as this medication can cause increased urination and nocturia (nighttime urination). Clients should take this medication in the morning or at least 6 hours before bedtime to avoid disrupting their sleep.
Choice D reason: Monitoring for leg cramps is an important instruction for clients taking hydrochlorothiazide, as this medication can cause muscle cramps due to electrolyte imbalances, such as hypokalemia, hyponatremia (low sodium levels), or hypomagnesemia (low magnesium levels). Clients should report any signs of muscle cramps, weakness, or fatigue to their provider.
