A patient is receiving gentamicin every 12 hours IVPB for an infection.

The nurse has administered the 0900 dose, which is prescribed to run over 1 hour. The physician prescribed peak and trough levels to be drawn.

When should the nurse expect to draw the peak level?

0930

1000

2030

2100

Answer and Explanation

The Correct Answer is B

Choice A rationale

Drawing the peak level at 0930, which is 30 minutes after the start of the infusion, would be too early. The medication would not have had enough time to reach its peak level in the blood.

Choice B rationale

The peak level of gentamicin is typically evaluated 30 minutes after the completion of the infusion. Since the infusion is administered over 1 hour, the peak level would be expected to be drawn at 10001.

Choice C rationale

Drawing the peak level at 2030, which is 12 hours after the start of the infusion, would not provide an accurate representation of the peak level of gentamicin. This is because the medication would have been metabolized and excreted over this period.

Choice D rationale

Drawing the peak level at 2100, which is 12.5 hours after the start of the infusion, would not provide an accurate representation of the peak level of gentamicin. This is because the medication would have been metabolized and excreted over this period.

Correct Answer is C

Explanation

Choice A rationale

Reddish feet when put down could be a sign of dependent rubor, a condition that occurs due to peripheral arterial disease (PAD). When the legs are in a dependent (downward) position, gravity aids in delivering blood to the area, causing a reddish color. However, this is a common symptom of PAD and does not require immediate intervention.

Choice B rationale

Loss of hair on the feet and legs is another symptom of PAD1. This happens because inadequate blood flow deprives the hair follicles of the nutrients they need to grow. While this symptom indicates worsening PAD, it does not warrant immediate intervention.

Choice C rationale

Applying a heating pad to cold legs could lead to burns because PAD can cause loss of sensation in the legs. This warrants immediate intervention to prevent injury.

Choice D rationale

Leg pain during walking, also known as claudication, is a common symptom of PAD1. This happens because the muscles are not getting enough oxygen due to reduced blood flow.

However, this symptom does not require immediate intervention but should be evaluated further.

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.
