A nurse is preparing to administer furosemide 30 mg IV bolus stat. Available is furosemide injection 10 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.)
Correct Answer: 3
Rationale: To determine the correct mL of furosemide to administer, we can use the formula: Desired dose (30 mg) / Available dose (10 mg/mL) = mL to administer. So, 30 mg / 10 mg/mL = 3 mL. The correct answer is therefore 3 mL.
Choice A: Incorrect. This answer does not provide the correct calculation based on the given information.
Choice B: Incorrect. This answer does not demonstrate the correct calculation based on the given information.
Choice C: Incorrect. This answer does not reflect the accurate calculation using the provided data.
Choice D: Incorrect. This choice does not show the correct calculation based on the information presented.
Choice E: Incorrect. This response does not align with the correct calculation method for determining the mL to administer.
Choice F: Incorrect. This choice does not offer the accurate calculation based on the provided data.
Choice G: Incorrect. This answer does not demonstrate the correct calculation using the

A nurse is caring for a client who is at risk for a pressure injury. Which of the following actions should the nurse take?
- A. Keep the head of the client’s bed elevated to 45
- B. Provide the client with a high-calorie diet
- C. Massage the client’s bony prominences
- D. Reposition the client every 4 hr
Correct Answer: B
Rationale: The correct answer is B: Provide the client with a high-calorie diet. A high-calorie diet can help promote tissue healing and prevent pressure injuries by providing the necessary nutrients for skin integrity. Keeping the head of the bed elevated to 45 degrees (A) is important for preventing aspiration but not directly related to preventing pressure injuries. Massaging bony prominences (C) can actually increase the risk of pressure injuries by causing friction and shear forces. Repositioning the client every 4 hours (D) is essential but not directly related to the prevention of pressure injuries.
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 is preparing to administer clonazepam 5 mg PO in 3 equally divided doses every 8 hr for a client who has seizures. The amount available is clonazepam 0.5 mg tablets. How many tablets should the nurse administer per dose? (Round off to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1
Rationale: Correct Answer: 1
Rationale: To calculate the number of tablets per dose, divide the total dose (5 mg) by the dose per tablet (0.5 mg).
5 mg / 0.5 mg = 10 tablets for the total dose.
Since the total dose is divided into 3 equal doses, divide the total tablets by 3.
10 tablets / 3 = 3.33 tablets per dose.
Round off to the nearest tenth, which is 3.3.
Since we cannot administer a partial tablet, the nurse should administer 1 tablet per dose.
Summary:
A: 1 - Correct. Calculated based on dividing total dose by dose per tablet and rounding off.
B: 2 - Incorrect. Not the correct calculation based on the dose per tablet.
C: 3 - Incorrect. Not the correct calculation based on the dose per tablet.
D: 4 - Incorrect. Not the correct calculation based on the dose per tablet.

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 teaching a client how to use crutches. Which of the following interventions uses the psychomotor domain of learning?
- A. Describe the steps of walking with crutches for the client
- B. Encourage the client to ask questions about walking with crutches
- C. Show the client a video on walking with crutches
- D. Ask the client to demonstrate walking with crutches
Correct Answer: D
Rationale: The correct answer is D: Ask the client to demonstrate walking with crutches. This intervention engages the psychomotor domain of learning by requiring the client to physically demonstrate the skill being taught. This hands-on approach helps the client develop muscle memory and coordination needed to effectively use crutches.
A, B, and C do not directly involve physical action or demonstration by the client. A describes verbal instruction, B encourages questioning and discussion, and C involves visual learning through a video. While these interventions are valuable in the learning process, they do not specifically target the physical practice of using crutches.
In summary, option D is the correct choice as it actively engages the client in practicing the skill, aligning with the psychomotor domain of learning.
