A nurse is caring for a client who had an arterial blood gas drawn. The pH on the ABG is 7.10. What acid-base imbalance does this client have?

Choice A Reason:

Listening to the client’s speech is not a method used to assess cranial nerve V. This method is more relevant for assessing cranial nerves IX (Glossopharyngeal) and X (Vagus), which are involved in speech and swallowing.

Choice B Reason:

Clenching the teeth is a method used to assess the motor function of cranial nerve V (the trigeminal nerve). The trigeminal nerve is responsible for the movement of the muscles involved in chewing. When a client clenches their teeth, the nurse can palpate the masseter and temporal muscles to check for strength and symmetry. This helps determine if there are any abnormalities in the motor function of the trigeminal nerve.

Choice C Reason:

Asking the client to read a Snellen chart is a method used to assess cranial nerve II (Optic), which is responsible for vision. This method does not assess cranial nerve V.

Choice D Reason:

Asking the client to raise his eyebrows is a method used to assess cranial nerve VII (Facial), which controls facial expressions. This method is not used to assess cranial nerve V.

Step-by-Step Calculation:

Step 1: Determine the dose required.

• Dose required = 1.5 mg

Step 2: Determine the dose available per tablet.

• Dose available per tablet = 0.5 mg

Step 3: Calculate the number of tablets needed.

• Number of tablets = Dose required ÷ Dose available per tablet
• Number of tablets = 1.5 mg ÷ 0.5 mg/tablet

Step 4: Perform the division.

• 1.5 ÷ 0.5 = 3

Result: The nurse should administer 3 tablets.

Therefore, the nurse should administer 3 tablets.
