Correct Answer: A

Rationale: To measure a client's calf circumference accurately, a nurse should place a non-stretchable tape measure around the widest point of the lower leg. It is crucial to ensure that the tape measure is positioned at the same number of centimeters down from a specific landmark, such as the patella, on both legs for consistency. Placing the tape measure 2 inches above the knee (Option B), 2 inches above the ankle (Option C), or 2 inches below the patella (Option D) would not provide an accurate measurement of the calf circumference. Therefore, these options are incorrect choices.

Correct Answer: D

Rationale: The correct answer is the statement, "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."? This statement would require correction from the nurse because initiating ART when the CD4 count is over 1,000 cells/mm3 is not supported by guidelines. The World Health Organization (WHO) recommends making treatment a priority for those with a CD4 count of ≤350 cells/mm3, as early intervention can help delay disease progression. Therefore, waiting for a CD4 count of over 1,000 cells/mm3 is not in line with current recommendations. Choice A is correct, as studies have shown that using condoms along with ART can significantly reduce the risk of HIV transmission to sexual partners. Choice B is also correct because being Hepatitis C positive does not contraindicate the use of ART. Choice C is correct as well, as ART is typically needed indefinitely to maintain viral suppression and manage HIV. Therefore, the only statement that would require correction is Choice D.

Correct Answer: D

Rationale: Lopressor is given to treat hypertension, and a pulse of 58 and a blood pressure of 90/62 are considered low. To prevent the client from bottoming out, the drug should be held, and the findings reported to the RN, who should consult with the attending physician. LPNs should never adjust client dosing, as that is outside of their scope of practice. It is crucial to follow facility guidelines, which often recommend holding blood pressure medication at 60 bpm and a systolic pressure of 90 or less. By holding the drug and notifying the RN, the LPN ensures the client's safety and allows for appropriate assessment and decision-making by the healthcare team. Giving half the dose or double the dose without proper authorization can lead to serious complications and is considered unsafe practice.

Correct Answer: B

Rationale: The nurse working with the client to explain what food and beverages might minimize aspiration is an example of secondary prevention. Secondary prevention involves early detection and intervention to prevent complications or worsening of a condition. In this case, the nurse is helping to prevent aspiration pneumonia by providing education and guidance on safe eating and drinking practices after the client has already experienced dysphagia due to a stroke. Choice A, health promotion, focuses on empowering individuals to adopt healthy behaviors to improve overall well-being and prevent illness. It is more about promoting general health rather than specific interventions related to a particular condition like dysphagia. Choice C, tertiary prevention, involves managing and rehabilitating a condition to prevent further complications or disabilities. In this scenario, the nurse is not yet addressing complications but rather actively preventing them. Choice D, primary prevention, aims to prevent the onset of a disease or condition before it occurs. The client in this case already has dysphagia, so the focus is on preventing further complications, making it a secondary prevention intervention.

Correct Answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.
