Patient in LTC with CLL, Activity Intolerance. Which activity to delegate to nursing assistant?

Correct Answer: B

Rationale: The correct answer is B: Check BP and pulse after ambulation. This task is appropriate to delegate to a nursing assistant as it involves monitoring vital signs post-activity, which is within their scope of practice. Nursing assistants are trained to perform basic assessments and report findings to the nurse. Choices A, C, and D involve assessing and making decisions about the patient's care, which should be done by a licensed nurse based on the patient's condition and individualized care plan. Checking BP and pulse after ambulation directly relates to the patient's activity intolerance and allows for immediate assessment of their response to activity, making it the most appropriate task to delegate in this scenario.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Plasma is the liquid portion of blood. 2. Phospholipid is a component of platelet membrane needed for coagulation. 3. Calcium is required for the activation of coagulation factors. Therefore, the correct answer is A. Summary: B: Thromboplastin is not an ingredient in PTT. C: Thromboplastin is not part of PTT. D: Thrombin is a product of the coagulation cascade, not an ingredient in PTT.

Correct Answer: A

Rationale: The correct answer is A: Alpha and beta. Hemoglobin A in normal adults consists of two alpha and two beta globin polypeptide chains. This is the most common form of hemoglobin in adults. The other choices (B: Alpha and epsilon, C: Alpha and delta, D: Alpha and brotherton) are incorrect because epsilon, delta, and brotherton are not the typical polypeptide chains found in adult hemoglobin. Hemoglobin F contains gamma and alpha chains, not epsilon or delta. Brotherton is not a known polypeptide chain in hemoglobin.

Correct Answer: C

Rationale: The correct answer is C: Rhodnius prolixus. This insect is a vector for Trypanosoma cruzi, causing Chagas disease. Palpebral edema, lymphadenopathy, and megaesophagus are common manifestations. Glossina morsitans transmits African Trypanosomiasis (sleeping sickness) with different symptoms. Ixodes scapularis transmits Lyme disease. Simulium damnosum transmits Onchocerciasis (river blindness). Thus, Rhodnius prolixus is the correct vector based on the provided symptoms.

Correct Answer: B

Rationale: The correct answer is B: Glutathione reduction. NADPH generated from the pentose phosphate pathway in RBCs is crucial for maintaining reduced glutathione levels, which helps protect cells from oxidative damage. Glutathione is an important antioxidant in cells that helps neutralize harmful reactive oxygen species. This process is essential for the protection of RBCs from oxidative stress and maintains their structural integrity. A: Fatty acid synthesis - NADPH is indeed required for fatty acid synthesis, but in RBCs, the primary role of NADPH is in maintaining redox balance rather than fatty acid synthesis. C: ATP formation - NADPH is not directly involved in ATP formation, as ATP is mainly produced through processes like glycolysis and oxidative phosphorylation. D: Oxygen radical removal - While NADPH is involved in reducing oxidative stress, its primary role in RBCs is to maintain glutathione levels for antioxidant defense rather than directly removing oxygen radicals.
