A nurse is caring for a client who reports taking 0.5 oz of diphenhydramine elixir every night to sleep. The concentration on the client's bottle reads diphenhydramine 12.5 mg/5 mL. How many mg of diphenhydramine is the client taking each night? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["37.5"]
Volume = Desired Dose / Available Concentration
Available: 12.5 mg / 5 mL
=2.5 mg/mL
Volume in mL = 0.5 oz × 30 mL/oz = 15 mL
Desired Dose = Volume (mL) × Available Concentration (mg/mL)
= 15 mL × 2.5 mg/mL
Desired Dose = 37.5 mg

Explanation
Indication of potential improvement:
• Shortness of breath with exertion
• Lung sounds clear
Indication of potential worsening condition:
• WBC count 11,800/mm³
• Temperature 38.5°C (101.3°F)
• Weight 113 kg (249 lb)
• Creatinine 1.8 mg/dL
Rationale:
• Shortness of breath with exertion: Previously, the client had dyspnea at rest. Improvement to exertional dyspnea suggests better fluid balance and cardiac function.
• Lung sounds clear: The initial presence of crackles indicated pulmonary congestion. Clear lung sounds suggest reduced fluid overload, reflecting improved cardiac function.
• WBC count 11,800/mm³: An increasing WBC count suggests a possible infection, which can worsen heart failure by increasing metabolic demands and fluid retention.
• Temperature 38.5°C (101.3°F): Fever indicates a possible infection, such as a UTI, which the client has a history of. Infections can exacerbate heart failure by triggering systemic inflammation and fluid shifts.
• Weight 113 kg (249 lb): Weight gain in heart failure is often due to fluid retention, indicating worsening congestion.
• Creatinine 1.8 mg/dL: A rising creatinine level suggests worsening kidney function, which may result from reduced perfusion due to heart failure or excessive diuresis from furosemide.
Correct Answer is B
Explanation
A. "The surgeon will make a small incision in your abdomen.": A hysterosalpingography is a fluoroscopic imaging procedure that does not require surgical incisions. Contrast dye is injected through the cervix to visualize the uterus and fallopian tubes.
B. "You may experience referred shoulder pain.": Referred shoulder pain is a common side effect due to peritoneal irritation caused by the contrast dye if it spills into the peritoneal cavity, particularly when the fallopian tubes are patent. This discomfort is temporary and resolves on its own.
C. "Your procedure will be scheduled during menstruation.": The test is typically scheduled after menstruation but before ovulation (days 7-10 of the cycle) to ensure the uterus is clear of blood and to avoid disrupting an early pregnancy.
D. "Warm saline will be instilled via the cervix.": Hysterosalpingography uses iodine-based contrast dye for X-ray imaging, not warm saline. Saline infusion is used in sonohysterography, which is an ultrasound-based procedure.
