A nurse is preparing to administer labetalol 40 mg IV to a client. Available is labetalol 5 mg/mL. 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 ["8"]
Calculation:
Desired dose = 40 mg.
Available concentration = 5 mg/mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 40 mg / 5 mg/mL
= 8 mL.

Correct Answer is B
Explanation
Rationale:
A. Autonomy: Autonomy involves respecting a client’s right to make their own healthcare decisions. While important, this scenario concerns unequal treatment rather than limiting the clients’ decision-making rights.
B. Justice: Justice refers to fairness and equity in the distribution of healthcare resources. Providing supplies to one client based on insurance status while denying them to another reflects unequal and unethical treatment, violating the principle of justice.
C. Beneficence: Beneficence means acting in the best interest of the client by promoting well-being. Although the insured client is benefitting, failing to support the uninsured client equally undermines the overall intent to do good for all clients.
D. Nonmaleficence: Nonmaleficence is the obligation to do no harm. While denying supplies could lead to harm, the primary ethical breach in this situation lies in the unfair distribution of care, which relates more directly to justice.
Correct Answer is C
Explanation
Rationale:
A. Take mineral oil at bedtime: Mineral oil is not recommended for long-term use because it can interfere with absorption of fat-soluble vitamins and may lead to aspiration pneumonia, especially in older adults. Safer stool softeners or laxatives should be used for opioid-induced constipation.
B. Decrease insoluble fiber intake: Insoluble fiber, such as wheat bran, helps bulk the stool and promote bowel movements. Reducing fiber intake can worsen constipation rather than relieve it, especially in clients taking opioids.
C. Increase exercise activity: Regular physical activity stimulates peristalsis and helps prevent constipation. Movement is a key non-pharmacologic strategy to counteract the slowed gastrointestinal motility caused by opioids.
D. Drink 1.5 L of fluids each day: Although hydration is important, adults typically require around 2 to 3 liters of fluid daily unless contraindicated. Limiting intake to 1.5 L may be insufficient to support normal bowel function and soften stool.
