What size of suction catheter would Wilma use for James, who is 6 feet 5 inches in height and weighing approximately 145 lbs?

Correct Answer: A

Rationale: The correct size of suction catheter for James would be Fr. 5. The selection of suction catheter size is based on the patient's height and weight, as well as the secretions to be cleared. A Fr. 5 catheter is appropriate for an average adult like James, as it balances between being too small or too large. Fr. 12 and Fr. 18 are too large for his size and could cause trauma, while Fr. 10 is slightly larger than needed, increasing the risk of mucosal damage. Therefore, Fr. 5 is the most suitable choice for James.

Correct Answer: C

Rationale: The correct answer is C because a decreased number of functioning acetylcholine receptor sites would result in the disease. Acetylcholine is a neurotransmitter that transmits signals between nerves and muscles. If there are fewer receptor sites for acetylcholine to bind to, this can lead to impaired nerve-muscle communication, causing the disease. Choice A is incorrect because a genetic defect in acetylcholine production would not directly affect the receptor sites. Choice B is incorrect because a reduced amount of acetylcholine would still be able to bind to the available receptor sites. Choice D is incorrect because inhibiting the enzyme Ache would not directly impact the receptor sites.

Correct Answer: B

Rationale: The correct answer is B because monitoring for swelling and heaviness of legs is essential in preventing falls, which can be caused by conditions like edema or circulatory issues. Swollen or heavy legs can affect mobility and balance, increasing the risk of falls. This intervention helps identify potential issues early and implement preventive measures. Choice A is incorrect as monitoring for chest pain and LDL levels pertains more to cardiovascular health than fall prevention. Choice C is incorrect because monitoring postural changes in BP is important for managing hypertension, not necessarily for preventing falls. Choice D is incorrect as monitoring temperature for mild fever is more related to identifying infections rather than preventing falls.

Correct Answer: C

Rationale: The correct answer is C because in myasthenia gravis, which is characterized by muscle weakness and fatigue, the administration of edrophonium will temporarily improve muscle strength due to increased availability of acetylcholine at the neuromuscular junction. This improvement should be noted within 30 to 60 seconds after the administration of the medication. Choice A is incorrect because joint pain is not a typical response to edrophonium in the context of myasthenia gravis. Choice B is incorrect because feelings of faintness, dizziness, hypotension, and flushing are more indicative of a cholinergic crisis, which occurs when too much edrophonium is administered. Choice D is incorrect because an increase in muscle strength post-edrophonium administration would not be expected in a client with myasthenia gravis.

Correct Answer: B

Rationale: The correct answer is B: An above-normal anti-deoxyribonucleic acid. In SLE, the body produces antibodies against its own DNA, leading to the presence of anti-dsDNA antibodies. Elevated levels of anti-dsDNA antibodies are specific to SLE, confirming the diagnosis. A: Increased total serum complement levels are seen in SLE due to complement activation but are not specific to SLE. C: Negative antinuclear antibody test is not consistent with SLE, as ANA positivity is common in SLE. D: Negative lupus erythematosus cell test is not specific to SLE as lupus erythematosus cells are not always present.
