Nursing Elites

1. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?

• A. Constipation
• B. Polyuria
• C. Rash
• D. Tinnitus

Correct answer: B

Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.

2. Which of the following statements best describes compartment syndrome?

• A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
• B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
• C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
• D. An injury causes pain and swelling of the median plantar nerve.

Correct answer: B

Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.

3. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?

• A. Peaked T waves on the ECG
• B. Muscle spasms
• C. Constipation
• D. A prominent U wave on the ECG

Correct answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

4. Which of the following situations might warrant a laboratory magnesium level?

• A. Hyperthyroidism
• B. Arthritis
• C. Ulcerative colitis
• D. Depression

Correct answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.

5. Which of these statements best describes the characteristics of an effective reward feedback system?

• A. Specific feedback is given as close to the event as possible
• B. Staff is given feedback in equal amounts over time
• C. Positive statements precede negative statements
• D. Performance goals should be higher than what is attainable

Correct answer: A

Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.
