A nurse is teaching a newly licensed nurse about ergonomic principles. Which of the following actions by the nurse indicates an understanding of the teaching?
- A. Stands with feet shoulder-width apart when lifting a client up in bed.
- B. Raises the client's knees before pulling the client up in bed.
- C. Uses a mechanical lift to move a client from bed to chair.
- D. Places a gait belt around the client's waist before assisting the client to stand.
Correct Answer: C
Rationale: Using a mechanical lift is an appropriate ergonomic technique as it reduces the risk of injury to both the nurse and the client by promoting safe client handling practices. Choice A is incorrect as standing with feet shoulder-width apart provides better balance and stability during lifting. Choice B is incorrect as raising the client's knees is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's waist is a safety measure but does not specifically demonstrate an understanding of ergonomic principles.

A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?
- A. aPTT 75 seconds.
- B. INR 1.2.
- C. Hemoglobin 10 g/dL.
- D. Fibrinogen level 350 mg/dL.
Correct Answer: A
Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.
A healthcare provider is assessing a newborn who has a patent ductus arteriosus. Which of the following findings should the provider expect?
- A. Continuous murmur.
- B. Absent peripheral pulses.
- C. Increased blood pressure.
- D. Bounding pulses.
Correct Answer: A
Rationale: A continuous murmur is a classic finding in a newborn with patent ductus arteriosus. This murmur is typically heard between the first and second heart sounds and throughout systole. Absent peripheral pulses (choice B) are not typically associated with patent ductus arteriosus. Increased blood pressure (choice C) and bounding pulses (choice D) are not commonly seen with this condition. Therefore, the correct answer is A.
A nurse is caring for a client who is postoperative following a thyroidectomy. The nurse should identify that which of the following client reports is an indication of hypocalcemia?
- A. Constipation
- B. Frequent urination
- C. Numbness and tingling of the fingers
- D. Increased thirst
Correct Answer: C
Rationale: The correct answer is C: 'Numbness and tingling of the fingers.' Post-thyroidectomy, hypocalcemia is a concern due to potential damage to the parathyroid glands that regulate calcium levels. Numbness and tingling of the fingers are classic signs of hypocalcemia. Constipation (Choice A) is not typically associated with hypocalcemia. Frequent urination (Choice B) is more indicative of conditions like diabetes or a urinary tract infection. Increased thirst (Choice D) is commonly seen in conditions such as diabetes insipidus or uncontrolled diabetes mellitus, not specifically related to hypocalcemia.
A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Serum sodium.
- B. Serum glucose.
- C. Serum potassium.
- D. Serum calcium.
Correct Answer: C
Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.
A nurse is teaching a client who has hypertension about managing blood pressure. Which of the following statements should the nurse make?
- A. Increase your intake of red meat to manage your blood pressure.
- B. You should avoid drinking alcohol while taking this medication.
- C. Exercise for at least 30 minutes most days of the week.
- D. Limit your fluid intake to 3 liters per day.
Correct Answer: C
Rationale: The correct statement is C: 'Exercise for at least 30 minutes most days of the week.' Regular exercise is essential in managing blood pressure as it helps improve cardiovascular health. Choice A is incorrect as increasing red meat intake can be detrimental due to its high saturated fat content, which can negatively impact blood pressure. Choice B is not directly related to managing blood pressure unless the medication interacts negatively with alcohol. Choice D, limiting fluid intake to 3 liters per day, is not a general recommendation for managing blood pressure unless specifically advised by a healthcare provider.
