A nurse is providing discharge instructions to a patient about self-administration of regular insulin. Which of the following instructions should be included by the nurse?

Choice A rationale:

Temperature is not a contraindication to cefazolin administration. While fever or temperature might indicate an infection or other condition that needs to be addressed, it does not by itself contraindicate the use of cefazolin. Cefazolin is an antibiotic, and its administration should be based on the presence of an infection and not solely on temperature readings.

Choice B rationale:

Allergy history is a significant contraindication for administering cefazolin. If the client has a known allergy or hypersensitivity to cefazolin or other cephalosporins, administering this medication could cause a severe allergic reaction, including anaphylaxis. Always review the client's allergy history before administering any medication to avoid such adverse effects.

Choice C rationale:

WBC count, although elevated in this scenario (13,000/mm³), is not a contraindication for cefazolin administration. An elevated WBC count may suggest an infection or inflammation, which might actually indicate a need for antibiotic therapy rather than contraindicate it.

Choice D rationale:

Amylase level is within normal range (80 units/L), so it does not contraindicate cefazolin administration. Elevated or abnormal amylase levels would be more relevant to concerns about pancreatitis or other pancreatic issues, but in this case, the level does not suggest a contraindication for cefazolin.

Choice E rationale:

Prescription for furosemide is relevant to consider as a potential contraindication due to the risk of nephrotoxicity. Cefazolin and furosemide both have the potential to impact kidney function. Using these medications together may increase the risk of renal impairment, especially in patients with pre-existing renal conditions. Therefore, it's important to monitor renal function closely when these medications are used together.

Choice A rationale

Metoprolol is a beta-blocker that affects the heart and circulation. It does not typically cause elevated blood glucose levels.

Choice B rationale

Metoprolol is used to treat high blood pressure, not increase it. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

Choice C rationale

Metoprolol does not typically reduce bronchospasms. In fact, it can sometimes cause breathing problems such as shortness of breath, cough, and wheezing.

Choice D rationale

Metoprolol is known to lower heart rate. This is one of the ways it helps to reduce blood pressure and relieve strains on the heart.
