A client has been prescribed nifedipine for angina. What is the priority assessment for the nurse to make prior to giving this medication?

Choice A reason: How to check apical heart rate is not a priority education for this client. Apical heart rate is the number of heartbeats per minute that can be heard at the apex of the heart. It can be used to monitor the effect of cardiac medications, such as atenolol or digoxin. This client is taking atenolol, but the nurse can check the client's radial pulse (at the wrist) instead of the apical pulse, unless there is a discrepancy or an irregular rhythm. The nurse should teach the client how to check their radial pulse and report any changes or symptoms.

Choice B reason: Signs and symptoms of hypothyroidism are not a priority education for this client. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, which regulate the metabolism and energy of the body. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, and depression. This client is not taking any medication that affects the thyroid function, and there is no evidence of hypothyroidism in the client's history or labs. The nurse should assess the client's thyroid function and teach the client about the signs and symptoms of thyroid disorders.

Choice C reason: Bleeding precautions are a priority education for this client. Bleeding precautions are measures to prevent or minimize bleeding in clients who are at risk of bleeding, such as those who are taking anticoagulants, have low platelets, or have bleeding disorders. This client is taking warfarin, an anticoagulant that increases the risk of bleeding.

Choice D reason: Increasing potassium rich foods in the diet is not a priority education for this client. Potassium is a mineral that helps regulate the fluid balance, nerve impulses, and muscle contractions in the body. Potassium levels can be affected by medications, such as diuretics, ACE inhibitors, or potassium supplements. This client is taking captopril, an ACE inhibitor that can increase the potassium level in the blood. The client's potassium level is normal (4.8 mmol/L), and there is no need to increase the intake of potassium rich foods, such as bananas, oranges, potatoes, tomatoes, or beans. The nurse should monitor the client's potassium level and teach the client about the signs and symptoms of high or low potassium, such as muscle weakness, cramps, irregular heartbeat, or numbness.

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.
