A nurse is preparing to lift a heavy object. Which of the following actions by the nurse indicates understanding of body mechanics?
- A. They bend at the hip when lifting
- B. They keep their feet together when lifting an object
- C. They stand close to the object being moved
- D. They twist their spine when lifting
Correct Answer: C
Rationale: The correct answer is C: They stand close to the object being moved. This action indicates understanding of body mechanics as it reduces the strain on the back by keeping the load close to the body's center of gravity. Standing close to the object allows for better leverage and control during the lift, minimizing the risk of injury.
Rationale for why other choices are incorrect:
A: Bending at the hip when lifting can put excessive strain on the lower back.
B: Keeping feet together may lead to instability and lack of balance during lifting.
D: Twisting the spine when lifting can result in spinal injuries and muscle strain.

A nurse is assessing a client for orthostatic hypotension. Which of the following actions should the nurse take first?
- A. Assist the client into a standing position
- B. Check the blood pressure with the client in a supine position
- C. Determine the client's blood pressure 1 min after each position change
- D. Place the client in a sitting position
Correct Answer: B
Rationale: The correct answer is B: Check the blood pressure with the client in a supine position. This is the first action the nurse should take because it establishes the baseline blood pressure of the client in a resting position. Orthostatic hypotension is characterized by a drop in blood pressure upon standing. By measuring the blood pressure in a supine position first, the nurse can accurately assess the extent of the blood pressure change when the client stands up.
Choices A, C, and D are incorrect because they involve positioning changes before establishing the baseline blood pressure. It is crucial to first determine the baseline blood pressure to accurately diagnose orthostatic hypotension. Choice A (Assist the client into a standing position) and D (Place the client in a sitting position) may exacerbate the client's symptoms if orthostatic hypotension is present. Choice C (Determine the client's blood pressure 1 min after each position change) is premature without knowing the baseline blood pressure.
A nurse is assessing a client who has a wound that is healing by primary intention. Which of the following findings should the nurse expect?
- A. Granulation tissue forming at the bottom of the wound bed
- B. Healing of the wound is prolonged
- C. Skin edges of the wound are sutured closed
- D. Wound is contaminated at the time of injury
Correct Answer: C
Rationale: The correct answer is C: Skin edges of the wound are sutured closed. In primary intention healing, the wound edges are approximated and closed with sutures, promoting faster healing and minimal scarring. Granulation tissue (A) is seen in secondary intention healing. Healing is not prolonged (B) in primary intention healing. Wound contamination (D) is not a characteristic of primary intention healing.
A nurse is preparing to administer an ophthalmic medication to a client. Which of the following actions should the nurse plan to take?
- A. Apply pressure to the client’s nasolacrimal duct after instillation
- B. Clean the client's eye from the outer canthus to the inner canthus before instillation
- C. Ask the client to tightly squeeze their eyes shut after the instillation
- D. Instill the ophthalmic medication directly on the client's cornea
Correct Answer: A
Rationale: The correct answer is A: Apply pressure to the client’s nasolacrimal duct after instillation. This action helps prevent systemic absorption of the medication and decreases the risk of side effects. By gently pressing on the nasolacrimal duct, the nurse can reduce the systemic absorption of the medication and promote its local effects. This technique is crucial for ophthalmic medications to work effectively and minimize adverse reactions.
Choice B is incorrect because cleaning the eye from outer to inner canthus can introduce contaminants into the eye, increasing the risk of infection. Choice C is incorrect as tightly squeezing the eyes shut can also lead to systemic absorption of the medication. Choice D is incorrect as instilling the medication directly onto the cornea can be harmful and may not distribute the medication effectively.
A nurse on a medical unit is reviewing the laboratory reports for a client. Which of the following laboratory values is the priority to report to the provider?
- A. Potassium level 3 mEq/L
- B. BUN 9.5 mg/dL
- C. Creatinine 0.4 mg/dL
- D. Sodium 135 mEq/L
Correct Answer: A
Rationale: The correct answer is A: Potassium level 3 mEq/L. A potassium level of 3 mEq/L is below the normal range (3.5-5.0 mEq/L), indicating hypokalemia. Hypokalemia can lead to serious cardiac arrhythmias. Therefore, it is crucial to report this abnormal potassium level promptly to the provider for further evaluation and intervention.
B: BUN 9.5 mg/dL - This is within the normal range (7-20 mg/dL) and does not require immediate intervention.
C: Creatinine 0.4 mg/dL - This is within the normal range (0.6-1.2 mg/dL) and does not indicate an urgent issue.
D: Sodium 135 mEq/L - This is within the normal range (135-145 mEq/L) and does not require immediate action.
A nurse is preparing to administer digoxin 5 mg PO to a client. The amount available is digoxin 0.5 mg/tablet. How many tablets 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.)
Correct Answer: 10
Rationale: The correct answer is 10 tablets. To calculate, you divide the total dose needed (5 mg) by the dose per tablet (0.5 mg). 5 mg ÷ 0.5 mg = 10 tablets. The nurse should administer 10 tablets of digoxin to achieve the desired 5 mg dose. Other choices are incorrect because they do not result in the correct dosage amount required for the client.
