A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr. to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mile How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
Given:
Diphenhydramine syrup: 12.5 mg/5 MLX
Required dose: 25 mg
First, determine the ratio of the available dosage strength to the required dose:
12.5 mg (available dose) / 5 mL (volume) = 25 mg (required dose) / X mL
Cross-multiply to find X (the amount of syrup needed):
12.5 mg X mL = 25 mg 5 mL
Now, solve for X:
X = (25 mg 5 mL) / 12.5 mg
X = 125 / 12.5
X = 10
Therefore, the nurse should administer 10 mL of diphenhydramine syrup to provide a dose of 25 mg to the older adult client with rhinitis.

Correct Answer is B
Explanation
Choice A Reason:
Requesting a dosage increase if the apical heart rate is less than 60/min is not necessary. Propranolol is used to lower heart rate in conditions like atrial fibrillation, so a heart rate below 60/min might be the desired effect of the medication.
Choice B Reason:
Withholding the medication if the systolic blood pressure is less than 90 mm Hg is necessary. Propranolol is a beta-blocker that can lower blood pressure. If the systolic blood pressure drops below 90 mm Hg, withholding the medication is necessary to prevent further lowering of blood pressure, which could lead to adverse effects like dizziness, fainting, or inadequate blood perfusion to vital organs.
Choice C Reason:
Administering the medication with an antacid might interfere with the absorption of propranolol, so they shouldn't be taken together unless instructed by the healthcare provider.
Choice D Reason:
Expecting increased hair growth is not an anticipated effect of propranolol. Hair growth is not a usual side effect associated with this medication.
Correct Answer is B
Explanation
Choice A Reason:
"I can take my partner outside of the room as long as they wear a mask."MRSA contact precautions typically involve limiting the spread of the bacteria. Taking the partner outside the room while wearing a mask might not be sufficient for infection control, as MRSA can spread through direct contact with surfaces. This statement might not indicate a full understanding of MRSA precautions.
Choice B Reason:
"I will wash my hands as soon as I leave the room. “Hand hygiene is a crucial component of infection control for MRSA. Washing hands with soap and water or using alcohol-based hand sanitizer after leaving the room helps prevent the spread of MRSA to oneself or others.
Choice C Reason:
"I will wear a gown when I help my partner take a bath." Wearing a gown during tasks that might involve contact with the patient's bodily fluids or surfaces that might be contaminated is recommended for MRSA precautions. This statement aligns with infection control practices.
Choice D Reason:
"I can reuse unsoiled gloves when I re-enter the room. “Reusing gloves, even if they appear unsoiled, is generally not recommended as it can contribute to the spread of MRSA. Gloves should be disposed of after each use and hands washed thoroughly.
