Jane, a 20-year old college student is admitted to the hospital with a tentative diagnosis of myasthenia gravis. She is scheduled to have a series of diagnostic studies for myasthenia gravis, including a Tensilon test. In preparing her for this procedure, the nurse explains that her response to the medication will confirm the diagnosis if Tensilon produces:
The client shows a marked improvement of muscle strength.
The client has muscles become weakened due to the impaired ability to respond to nerve signals
There is reduced amplitude of electrical stimulation in the muscle.
The anti-acetylcholine receptor antibodies are present.
The Correct Answer is A
Choice A rationale: The Tensilon test involves injecting edrophonium, and in myasthenia gravis, temporary improvement in muscle strength confirms the diagnosis by demonstrating increased acetylcholine activity at the neuromuscular junction.
Choice B rationale: This describes the pathophysiology of myasthenia gravis but doesn’t directly confirm the diagnosis via the Tensilon test.
Choice C rationale: While this may be seen in myasthenia gravis, the Tensilon test specifically aims to observe improved muscle strength after administration.
Choice D rationale: While the presence of these antibodies is a characteristic of myasthenia gravis, the Tensilon test is used to assess the immediate response to the medication for diagnostic confirmation.

Correct Answer is C
Explanation
Choice A rationale: Assessing the UOP is important, but not as urgent as correcting the potassium imbalance.
Choice B rationale: Obtaining a 12-lead ECG can help monitor the cardiac status, but it does not address the cause of the problem.
Choice C rationale: The PMHCP can order potassium replacement to prevent cardiac arrhythmias and other adverse effects of low potassium levels.
Choice D rationale: Stopping the regular insulin infusion can worsen the DKA and increase the risk of cerebral edema and coma.
Correct Answer is C
Explanation
Choice A rationale: This question is not relevant to BPH, as erectile dysfunction is not a common complication of this condition. Erectile dysfunction can have other causes, such as cardiovascular disease, diabetes, medications, psychological factors, or aging.
Choice B rationale: This question is not relevant to BPH, as penile discharge is not a symptom of this condition. Penile discharge can indicate an infection, such as sexually transmitted diseases, urinary tract infections, or prostatitis.
Choice C rationale: BPH is a condition that causes enlargement of the prostate gland, which can obstruct the flow of urine and cause symptoms such as difficulty in starting or stopping urination, weak or intermittent stream, dribbling, and incomplete bladder emptying. Asking about the force of the urinary stream can help assess the severity of BPH and the need for treatment.
Choice D rationale: This question is not relevant to BPH, as sexual function is not directly affected by this condition. However, some men with BPH may experience reduced libido or satisfaction due to urinary symptoms or psychological distress.
