The healthcare provider prescribes penicillin 200,000 units IM for a client with pneumonia. The available vial is labeled, "Penicillin 500,000 units/mL. How many mL should the nurse administer to this client?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
To determine the correct dosage, the nurse needs to perform a calculation using the information provided. The prescription is for 200,000 units of penicillin, and the available vial concentration is 500,000 units per mL.
To find out how many mLs to administer, the nurse would divide the prescribed units by the concentration of units per mL. This is calculated as 200,000 units divided by 500,000 units/mL, which equals 0.4 mL.

Correct Answer is ["A","B","C","D","F"]
Explanation
A. The patient’s oxygen saturation remains below the target of 94% despite initial oxygen therapy. Therefore, increasing the oxygen flow might be necessary to achieve better oxygenation.
B. Since the patient remains symptomatic with ongoing wheezes, administering another dose of the nebulizer treatment as ordered, since the prescription included PRN can help to further open the airways and alleviate wheezing.
C. Elevating the head of the bed can help improve lung expansion and ease the work of breathing, which is particularly beneficial in respiratory distress situations.
D. Switching to a nonrebreather mask may be appropriate if the patient’s oxygen saturation does not improve sufficiently with the current method of oxygen delivery. This type of mask can deliver a higher concentration of oxygen.
E. While incentive spirometry is generally used for preventing pulmonary complications (such as pneumonia or atelectasis) after surgery or in conditions where patients are likely to be immobile, it may not be immediately beneficial or a priority in the acute management of an asthma attack. The primary focus should be on stabilizing the patient’s respiratory status through medication and oxygen therapy. Thus, this option is less critical at this stage.
F. Continuous monitoring of vital signs is crucial in acute cases like this to assess the patient's response to interventions and detect any deterioration in the clinical status.
