The nurse is giving the vasodilator medication hydralazine IV push to a client with a systolic blood pressure of 210. What nursing education would be most important to include for this client?
Immediately report a dry cough
Low heart rate is common with this medication
Do not take this medication with birth control
Do not get up without assistance
The Correct Answer is D
Choice A reason: This is incorrect because a dry cough is not a common or serious side effect of hydralazine. A dry cough is more likely to occur with angiotensin-converting enzyme (ACE) inhibitors, which are another class of antihypertensive drugs.
Choice B reason: This is incorrect because hydralazine does not cause a low heart rate. In fact, hydralazine can cause a reflex increase in heart rate as a result of lowering the blood pressure. This is why hydralazine is often given with a beta-blocker, which can slow down the heart rate.
Choice C reason: This is incorrect because hydralazine does not interact with birth control. However, the nurse should advise the client to use effective contraception while taking hydralazine, as this medication can cause fetal harm if used during pregnancy.
Choice D reason: This is correct because hydralazine can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, and falls. The nurse should instruct the client to avoid getting up too quickly and to ask for assistance if needed.

Correct Answer is A
Explanation
Choice A reason: Elimination is the process of removing a drug from the body, usually through the kidneys or the liver. Acute renal failure is a condition where the kidneys suddenly lose their ability to filter waste products and excess fluid from the blood. This can impair the elimination of drugs that are mainly excreted by the kidneys, leading to increased drug levels and potential toxicity. The nurse should monitor the patient's renal function and adjust the dose of drugs that are renally eliminated.
Choice B reason: Metabolism is the process of transforming a drug into one or more metabolites, usually by enzymes in the liver. Acute renal failure does not directly affect the metabolism of drugs, unless it causes liver damage or alters the blood flow to the liver. The nurse should monitor the patient's liver function and the levels of drugs that are metabolized by the liver.
Choice C reason: Distribution is the process of transferring a drug from the blood to the tissues and organs of the body. Acute renal failure can affect the distribution of drugs that are bound to plasma proteins, such as albumin. When the kidneys are damaged, they may leak protein into the urine, causing hypoalbuminemia (low levels of albumin in the blood). This can increase the amount of free or unbound drug in the blood, which may enhance the drug's effect or cause adverse reactions. The nurse should monitor the patient's serum albumin level and the effects of drugs that are highly protein bound.
Choice D reason: Absorption is the process of moving a drug from the site of administration to the bloodstream. Acute renal failure does not directly affect the absorption of drugs, unless it causes changes in the gastrointestinal tract, such as edema, bleeding, or motility disorders. The nurse should monitor the patient's gastrointestinal function and the bioavailability of drugs that are administered orally.
Correct Answer is ["5"]
Explanation
To calculate the amount of megestrol oral suspension that the nurse should administer, we can use the following formula:
Amount to administer (mL) = (Desired dose in mg) / (Amount of drug in 1 mL)
Given:
Desired dose = 200 mg
Amount of drug in 1 mL = 40 mg/mL
Now, let's calculate the amount to administer:
Amount to administer (mL) = 200 mg / 40 mg/mL
Amount to administer (mL) = 5 mL
Rounding to the nearest whole number, the nurse should administer 5 mL of the megestrol oral suspension.
