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 B
Explanation
A. Prepare to assist in applying a new cast to reduce pressure points: Recasting is unnecessary unless there is malalignment, skin compromise, or complications. Formation of a callus is a normal healing process and does not require a new cast.
B. Explain that this is an expected part of the bone healing process: A callus is new bone that forms around a fracture as part of natural healing. Educating the client helps reduce anxiety and reinforces understanding of normal fracture recovery milestones.
C. Report the client's concern to the healthcare provider: While documentation of client concerns is appropriate, reassurance and education about normal healing is the priority in this situation. There is no complication requiring provider intervention.
D. Teach the client strategies to prevent further calluses: Callus formation at the fracture site is a desired outcome of bone healing, not a preventable problem. Interventions to prevent calluses are unnecessary and would be misleading.
Correct Answer is D
Explanation
A. Emptying time of the stomach is increased in labor: Although gastric emptying is slowed during labor due to hormonal and physiological changes, this alone does not fully explain the restriction of oral intake. It contributes to delayed digestion but is not the primary safety concern.
B. Nausea occurs at the onset of labor: Nausea and vomiting can occur early in labor due to pain and hormonal shifts, but these symptoms alone do not justify withholding food. The more serious concern is the risk of aspiration during potential anesthesia or emergencies.
C. Blood is shunted from the gut during labor: While blood flow may decrease to nonessential organs, including the gastrointestinal tract, this change does not directly cause complications from eating during labor. It is not the main reason for dietary restriction.
D. There is increased risk of aspiration of gastric contents: The primary reason is to prevent aspiration if general anesthesia becomes necessary for emergency procedures, such as a cesarean section. A full stomach increases the chance of regurgitation and aspiration, leading to life-threatening complications like aspiration pneumonia.
