The healthcare provider prescribes penicillin 200,000 units intramuscularly for a patient with pneumonia.

The available vial is labeled “Penicillin 500,000 units/mL”. How much penicillin should be administered to the patient? (Enter numerical value only.

If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.4"]

Step 1 is to determine the amount of penicillin in each milliliter (mL) of the available solution. The vial is labeled as “Penicillin 500,000 units/mL”.

Step 2 is to divide the prescribed dose by the concentration per mL. So, the calculation is 200,000 units ÷ 500,000 units/mL. The result is 0.4 mL.

Correct Answer is D

Explanation

Diverticulitis is an inflammation or infection of the pouches formed in the colon. During an acute onset of diverticulitis, it’s important to rest the bowel to allow for healing. Therefore, maintaining the patient’s NPO (nothing by mouth) status would be the appropriate next step.

A. The patient should adjust their food intake to three full meals per day with no snacks. B. The patient should avoid participating in any aerobic exercise programs. C. The patient should sleep without pillows at night to maintain neck alignment. D. The patient should wear loose, comfortable clothing to minimize symptoms.

Correct Answer is D

Explanation

Choice A rationale
Adjusting food intake to three full meals per day with no snacks is not necessarily recommended for GERD patients. Smaller, more frequent meals can help prevent the stomach from becoming too full and causing reflux.
Choice B rationale
Avoiding participation in any aerobic exercise programs is not a general recommendation for GERD patients. While some exercises may worsen GERD symptoms, many forms of aerobic exercise can be performed without triggering symptoms.
Choice C rationale
Sleeping without pillows at night to maintain neck alignment is not typically recommended for GERD patients. Elevating the head of the bed can actually help prevent acid reflux during sleep.
Choice D rationale
Wearing loose, comfortable clothing can help minimize GERD symptoms. Tight clothing can put pressure on the abdomen and the lower esophageal sphincter, potentially causing reflux.
