A home care client takes isosorbide dinitrate 80 mg PO daily. The medication container is labeled, 40 mg per capsule and the practical nurse (PN) counts 4 remaining capsules. The PN should advise the client that there are sufficient capsules remaining for how many days? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["2"]
Calculate the total milligrams (mg) remaining in the container.
Available dosage = 40 mg per capsule
Number of capsules remaining = 4 capsules
Total mg remaining = 4 capsules × 40 mg/capsule
= 160 mg.
Prescribed dose = 80 mg PO daily.
Calculate the number of days the remaining medication will last.
Days supply = (Total mg remaining / Daily dose (mg/day))
= (160 mg / 80 mg/day)
= 2 days.

Correct Answer is D
Explanation
A. Lateral, semi-prone: This position provides limited access to one side of the posterior chest only, which restricts full assessment of both lung fields and may compromise accurate auscultation findings.
B. Semi-Fowler’s: While comfortable for breathing, this position does not allow the nurse to fully access the posterior lung areas, where lower-lobe sounds—such as crackles from pneumonia—are best heard.
C. Right side-lying: Positioning the client on the right side limits the ability to assess the left posterior lung fields and can mask abnormal breath sounds in the affected lobe.
D. Forward orthopneic: Sitting upright and leaning slightly forward allows the nurse to access all posterior lung fields clearly. This position also facilitates better expansion of the lungs, improving both auscultation accuracy and client comfort during assessment.
Correct Answer is B
Explanation
A. Forehead and face: The forehead and face may show subtle changes in color, but hyperpigmentation or natural skin tone variations can make it difficult to accurately assess pallor, cyanosis, or jaundice in clients with dark skin.
B. Sclera and mucous membranes: The sclera of the eyes and oral mucous membranes are reliable sites for assessing pallor, cyanosis, or jaundice in clients with dark skin because these areas have less pigmentation and allow better visualization of changes in tissue perfusion or oxygenation.
C. Hands and feet: While the hands and feet can sometimes indicate changes in circulation, they may also reflect natural variations in pigmentation, temperature, or peripheral blood flow, making assessment less reliable in darker-skinned clients.
D. Finger and toe nails: Nail beds can be examined for capillary refill and oxygenation, but darker nail beds or pigmentation may obscure subtle color changes, limiting their effectiveness as the primary site for assessment in clients with dark skin tones.
