The nurse is obtaining a systolic blood pressure by palpation. While inflating the cuff, the radial pulse is no longer palpable at 90 mm Hg. Which action should the nurse take?

Document the absence of the radial pulse.

Release the manometer valve immediately.

Inflate blood pressure cuff to 120 mm Hg.

Record a palpable systolic pressure of 90 mm Hg.

Answer and Explanation

The Correct Answer is C

A. Document the absence of the radial pulse:

While it's important to document findings accurately, it's also crucial to ensure that blood pressure measurements are obtained correctly. If the radial pulse becomes unpalpable before reaching the expected systolic pressure, further action is needed to obtain an accurate measurement.

B. Release the manometer valve immediately:

Releasing the manometer valve immediately would lead to deflating the cuff and potentially missing the opportunity to obtain an accurate blood pressure measurement. This action is not appropriate at this stage.

C. Inflate blood pressure cuff to 120 mm Hg:

When the radial pulse becomes unpalpable during cuff inflation, it indicates that the cuff pressure is above the systolic pressure. To accurately determine the systolic pressure, the cuff should be inflated to a higher pressure (usually 20-30 mm Hg above the point where the radial pulse disappears) and then slowly deflated while palpating for the return of the radial pulse.

D. Record a palpable systolic pressure of 90 mm Hg:

If the radial pulse is no longer palpable at 90 mm Hg, this suggests that the true systolic pressure is higher than 90 mm Hg. Recording a palpable systolic pressure of 90 mm Hg without further action would likely underestimate the true systolic pressure.

Correct Answer is A

Explanation

A. Provide a back rub at bedtime:

This intervention addresses the client's immediate need for comfort and relaxation without resorting to restrictive measures or medications.

B. Leave the door to the client's room open slightly:

Leaving the door open may not prevent wandering and could potentially lead to safety issues.

C. Apply wrist restraints to prevent wandering:

Restraints should only be used as a last resort and when all other interventions have failed. They pose risks to the client's physical and psychological well-being and should be avoided whenever possible.

D. Administer a PRN sedative prescription:

Sedatives should be used judiciously and only after other non-pharmacological interventions have been attempted. Sedating the client may increase the risk of falls or injury and should not be the first-line intervention for managing sleep disturbances or wandering behavior.

Correct Answer is ["1"]

Explanation

To determine how many tablespoons the client should take with each dose, we need to first calculate the dosage in tablespoons based on the concentration of the oral suspension.

Given:

Dextromethorphan oral suspension concentration: 30 mg per 15 mL

To find out how many milliliters the client should take per dose:

The prescribed dose is 30 mg.

So, if 15 mL contains 30 mg, then 1 mL contains:

30 mg / 15 mL = 2 mg/mL

To find out how many milliliters the client should take for the prescribed dose:

30 mg / 2 mg/mL = 15 mL

Now, we know that the prescribed dose is 15 mL. To convert this to tablespoons, we can use the fact that 1 tablespoon (tbsp) is equal to 15 milliliters.

So, the client should take:

15 mL / 15 mL/tbsp = 1 tablespoon

Therefore, the nurse should instruct the client to take 1 tablespoon with each dose.
