Correct Answer: B

Rationale: The correct answer is B: Pulse and blood pressure. Before administering beta-adrenergic blocking agents, the nurse should assess the patient's pulse and blood pressure because these medications can lower heart rate and blood pressure. Monitoring these parameters helps to ensure the medication is safe and appropriate for the patient. Weight and caloric intake (
Choice
A) are important for other assessments but not specifically necessary before administering beta-blockers. Serum sodium level (
Choice
C) and serum albumin level (
Choice
D) are not directly related to the administration of beta-blockers and would not impact the decision to administer these medications.

Correct Answer: C

Rationale:
Correct
Answer: C

Rationale: Taking furosemide in the morning minimizes nocturia and ensures proper diuresis during the day, reducing the risk of dehydration and electrolyte imbalance. This timing also prevents sleep disturbances.
Summary of Incorrect

Choices:
A: Limiting fluid intake while on furosemide can lead to dehydration and electrolyte imbalances.
B: Furosemide typically decreases blood pressure, so it is unlikely for it to increase while taking this medication.
D: Furosemide can cause potassium loss, so consuming a diet low in potassium can worsen this imbalance.

Correct Answer: D

Rationale: The correct answer is D: Review the client's electrolyte values. In a client with acute exacerbation of ulcerative colitis, electrolyte imbalances are common due to diarrhea and inflammation. Addressing electrolyte abnormalities is crucial to prevent complications like dehydration or cardiac arrhythmias. Checking perianal skin integrity (
A) is important but not the priority. Educating the patient on foods (
B) can wait until the immediate issue is addressed. Investigating emotional concerns (
C) is important but not as critical as addressing physiological needs. Reviewing electrolyte values (
D) is the first step in managing the client's condition.

Correct Answer: B,C,E

Rationale: The correct answer is B, C, and E. Myasthenia gravis is an autoimmune disease where the immune system attacks acetylcholine receptor sites on muscles, leading to muscle weakness and fatigue.
Choice B is correct as myasthenia gravis is thought to be an autoimmune disease.
Choice C is correct because it is associated with the destruction of acetylcholine receptor sites.
Choice E is correct as myasthenia gravis is a chronic and progressive muscular disease.

Choices A, D, and F are incorrect.
Choice A is incorrect because myasthenia gravis is not caused by demyelination of nerve fibers.
Choice D is incorrect because the survival rate varies and is not strictly limited to 5 years once symptoms present.
Choice F is incorrect because myasthenia gravis is not best treated with antibiotics; it is typically managed with medications that help improve neuromuscular transmission.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion as a side effect. Low potassium levels can lead to cardiac arrhythmias, which can worsen heart failure. Reviewing potassium levels before administering furosemide helps the nurse monitor the client's electrolyte balance and prevent potential complications.
Incorrect options:
A: Bicarbonate - Bicarbonate levels are not directly affected by furosemide administration.
C: Phosphate - Furosemide does not significantly impact phosphate levels.
D: Carbon dioxide - Carbon dioxide levels are not typically monitored in relation to furosemide therapy.
