A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?
- A. 0.4 mL
- B. 0.5 mL
- C. 0.6 mL
- D. 0.7 mL
Correct Answer: B
Rationale: To calculate the dose of enoxaparin, first convert the client's weight from pounds to kilograms: 154 lb/2.2 = 70 kg. Then, calculate the dose: 0.75 mg/kg x 70 kg = 52.5 mg. Since the concentration is 60 mg/0.6 mL, divide the dose needed by the concentration: 52.5 mg/60 mg x 0.6 mL = 0.5 mL. Therefore, the correct answer is B (0.5 mL). Choice A is incorrect as it is less than the calculated dose. Choice C is incorrect as it is based on the concentration but does not match the calculated dose. Choice D is incorrect as it is higher than the calculated dose.

A nurse is preparing to administer propranolol to several clients. For which of the following clients should the nurse clarify the prescription with the provider before administration?
- A. A client who has a history of asthma
- B. A client who has hypertension
- C. A client who has a history of migraines
- D. A client who has stable angina
Correct Answer: A
Rationale: The correct answer is A: A client who has a history of asthma. Propranolol is a non-selective beta-blocker that can potentially exacerbate bronchospasm in patients with asthma due to its mechanism of action. Therefore, the nurse should clarify the prescription with the provider before administering it to a client with asthma to avoid potential adverse effects. Choices B, C, and D are not contraindications for propranolol use, so there is no need to clarify the prescription for clients with hypertension, migraines, or stable angina.
A nurse is assessing a client who has suspected appendicitis. Which of the following manifestations should the nurse expect? (Select all that apply.)
- A. Right lower quadrant pain
- B. Rebound tenderness
- C. Nausea and vomiting
- D. Elevated blood glucose
- E. Hypotension
Correct Answer: A, B, C
Rationale: The correct manifestations for suspected appendicitis are A, B, and C. A is correct as appendicitis typically presents with right lower quadrant pain due to inflammation of the appendix. B is correct as rebound tenderness, which is pain upon release of pressure on the abdomen, is a classic sign of appendicitis. C is correct as nausea and vomiting are common symptoms due to irritation of the gastrointestinal tract. D and E are incorrect as elevated blood glucose and hypotension are not commonly associated with appendicitis.
A nurse is caring for a client who is hemorrhaging and hypotensive from esophageal variceal bleeding. Which of the following actions should the nurse take first?
- A. Administer a vasopressor.
- B. Verify that the client has adequate IV access.
- C. Place the client in the Trendelenburg position.
- D. Prepare for endoscopic intervention.
Correct Answer: B
Rationale: The correct answer is B: Verify that the client has adequate IV access. This is the priority action because the client is hypotensive from hemorrhaging, indicating a need for immediate fluid resuscitation to stabilize their condition. Without adequate IV access, the nurse cannot administer life-saving fluids and medications. Administering a vasopressor (A) or preparing for endoscopic intervention (D) may be necessary later but addressing the hypotension is the priority. Placing the client in Trendelenburg position (C) is not recommended as it can increase intracranial pressure.
A nurse is planning preventative strategies for a client who is at risk for pressure injuries. Which of the following actions should the nurse include in the plan?
- A. Apply moisturizer to damp skin after bathing.
- B. Massage bony prominences to improve circulation.
- C. Use cornstarch powder to keep skin dry.
- D. Position the client at a 90-degree angle in bed.
Correct Answer: A
Rationale: The correct answer is A: Apply moisturizer to damp skin after bathing. Moisturizing helps maintain skin integrity and hydration, reducing the risk of pressure injuries. When skin is damp, it is more receptive to hydration, which can prevent dryness and breakdown. Applying moisturizer also helps to maintain the skin's natural barrier function. Massaging bony prominences (choice B) can actually increase the risk of pressure injuries by causing friction and shearing forces. Using cornstarch powder (choice C) can lead to moisture buildup and increase the risk of skin breakdown. Positioning the client at a 90-degree angle in bed (choice D) is not a recommended preventive strategy for pressure injuries.
A nurse is planning care for a client who had a lumbar laminectomy. Which of the following interventions should the nurse include in the plan of care?
- A. Encourage the client to ambulate independently.
- B. Turn the client by log rolling with a turning sheet.
- C. Position the client in a high Fowlers position.
- D. Apply a heating pad to the lower back.
Correct Answer: B
Rationale: The correct answer is B: Turn the client by log rolling with a turning sheet. This is the correct intervention because after a lumbar laminectomy, it is crucial to protect the surgical site and avoid bending or twisting the spine. Log rolling with a turning sheet helps maintain proper alignment and prevent injury to the surgical area.
Choice A is incorrect because encouraging the client to ambulate independently may put stress on the surgical area. Choice C is incorrect as positioning the client in a high Fowler's position may also strain the spine. Choice D is incorrect because applying a heating pad to the lower back can increase the risk of burns and should be avoided near a surgical site.
