The nurse is preparing to administer an aminoglycoside antibiotic to a client admitted with a diagnosis of acute diverticulitis.
What is the priority nursing action?

Monitor the peak level of the antibiotic.

Assess the client’s vital signs.

Obtain a serum trough level.

Ask the client about drug allergies.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Monitoring the peak level of the antibiotic is important, but it is not the priority nursing action. Peak levels are typically drawn after the drug has been administered and are used to assess whether the dosage is sufficient.

Choice B rationale

Assessing the client’s vital signs is an important part of nursing care, but it is not the priority action when preparing to administer an aminoglycoside antibiotic.

Choice C rationale

Obtaining a serum trough level is the priority nursing action. Trough levels are drawn just before the next dose of the drug is due and are used to assess whether the dosage is safe.

Choice D rationale

Asking the client about drug allergies is an important part of nursing care, but it is not the priority action when preparing to administer an aminoglycoside antibiotic.

Correct Answer is C

Explanation

Choice A rationale

Heparin does not actually thin the blood or make it less thick. Instead, it works by increasing the activity of antithrombin, a protein that inhibits blood clotting. This prevents new clots from forming and existing clots from growing larger.

Choice B rationale

Heparin does not dissolve clots or decrease the formation of platelets. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa, two key players in the blood clotting process.

Choice C rationale

This statement is accurate. Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.

Choice D rationale

Heparin does not decrease the number of platelets or make the blood flow more easily. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa.

A. Metronidazole may cause constipation. B. Metronidazole can cause anxiety. C. Metronidazole may cause an unusual metallic taste in your mouth. D. Metronidazole will cause an upset stomach.

Correct Answer is C

Explanation

Choice A rationale

While constipation can be a side effect of many medications, it is not commonly associated with metronidazole.

Choice B rationale

Anxiety is not a common side effect of metronidazole. If a patient experiences anxiety while taking metronidazole, it’s important to discuss this with a healthcare provider as it may be related to other factors.

Choice C rationale

Metronidazole may cause an unusual metallic taste in the mouth. This is a common side effect of the medication and is usually temporary. Patients should be advised that if the metallic taste persists or becomes bothersome, they should consult their healthcare provider.

Choice D rationale

While metronidazole can cause gastrointestinal upset, it’s not guaranteed to cause an upset stomach in every patient. If a patient experiences persistent or severe gastrointestinal upset while taking metronidazole, they should consult their healthcare provider.
