foundations of nursing practice questions

Correct Answer: D

Rationale: The correct answer is D because saturated fats are primarily found in animal sources such as red meat, poultry, and dairy products. It is important to limit the intake of saturated fats on a low-fat diet to reduce the risk of heart disease and other health issues. A: Polyunsaturated fats are actually considered healthy fats and should not be restricted to less than 7% of total calories. B: Transfat is a type of unhealthy fat that should be avoided altogether, not just limited to 7% of total calories. C: Unsaturated fats are actually found mostly in plant-based sources like nuts, seeds, and avocados, not animal sources. In summary, choice D is correct because it provides accurate information about the source of saturated fats in animal products, while the other choices provide incorrect or misleading information about different types of fats.

Correct Answer: A

Rationale: The correct answer is A. Research studies have consistently shown that families' needs for information and support often go unmet in hospital settings when caring for dying patients. This is a crucial deficiency as effective communication and support for families can greatly impact the quality of care provided to the dying patient. When families are not adequately informed and supported, it can lead to increased stress, confusion, and dissatisfaction with the care provided. Choices B, C, and D are incorrect because they do not address the specific deficiency identified in research studies. While pain control, communication, and attention from caregivers are important aspects of end-of-life care, the primary focus in this scenario is on the unmet needs of families for information and support. Ignoring families' needs can have significant negative consequences on the overall care provided to the dying patient.

Correct Answer: C

Rationale: The correct answer is C: Western blot test. The Western blot test is considered the gold standard for confirming HIV diagnosis after a positive EIA result. It detects specific antibodies to HIV proteins, providing a more accurate confirmation. Other choices are incorrect because: A: Another EIA test would yield the same result as the initial EIA test. B: Viral load test measures the amount of virus in the blood and is not used to confirm HIV diagnosis. D: CD4/CD8 ratio is used to monitor immune status but not to confirm HIV diagnosis.

Correct Answer: B

Rationale: The correct answer is B: Jejunostomy tube. This tube is chosen because the patient has a history of aspiration pneumonia, which puts them at risk for aspiration if feeds are administered into the stomach. By administering feeds through a jejunostomy tube, the risk of aspiration pneumonia is minimized as the feed bypasses the stomach. Nasogastric tube (A) and Nasointestinal tube (C) would still deliver feeds to the stomach, increasing the risk of aspiration. PEG tube (D) is also not ideal as it delivers feeds directly to the stomach, which is not recommended for patients at risk for aspiration.

Correct Answer: A

Rationale: The correct answer is A: When the patient is resting. This is because the tremor associated with Parkinson's disease is most noticeable when the patient is at rest due to the characteristic "resting tremor" seen in this condition. The tremor tends to lessen or disappear with purposeful movements or activities, making it more difficult to assess during ambulation, meal preparation, or occupational therapy. By observing the patient at rest, the nurse can accurately assess the presence and severity of the tremor, which is a key diagnostic feature of Parkinson's disease. Other answer choices are incorrect because they do not provide the optimal condition for assessing the tremor associated with Parkinson's disease.
