Nursing Elites

1. 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.

2. Which example best describes a nurse who exhibits moral courage?

• A. A nurse feels angry when a parent refuses important treatment for his child.
• B. A nurse considers seeking help for depression when she feels she cannot meet the needs of her clients in the oncology unit.
• C. A nurse contacts a physician for further orders when he fails to order comfort measures for a client with a terminal illness.
• D. A nurse is frustrated when the laboratory is slow in responding to an order for a stat blood glucose.

Correct answer: C

Rationale: Moral courage involves taking action to do what is right, even when there might be negative consequences. The nurse who contacted a physician for further orders acted as a client advocate to seek help, even though she may have faced consequences such as lost time, decreased productivity, or criticism from the physician. Choices A, B, and D do not directly involve advocating for a client's needs or challenging a situation that goes against ethical standards. Feeling angry, seeking help for personal issues, or being frustrated with work processes do not necessarily demonstrate moral courage in the context of nursing practice.

3. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

4. When should discharge training and planning begin for a 65-year-old man admitted to the hospital for spinal stenosis surgery?

• A. Following surgery
• B. Upon admission
• C. Within 48 hours of discharge
• D. Preoperative discussion

Correct answer: B

Rationale: Discharge training and planning should begin upon admission for a patient undergoing spinal stenosis surgery. It is crucial to initiate this process early to ensure a smooth transition from hospital care to home or a rehabilitation facility. Starting discharge planning upon admission allows for comprehensive involvement of the patient, family, and healthcare team, which can reduce the risk of readmission, optimize recovery, ensure proper medication management, and adequately prepare caregivers. Therefore, option B, 'Upon admission,' is the correct answer. Options A, C, and D are incorrect because waiting until after surgery, within 48 hours of discharge, or during preoperative discussion would not provide sufficient time for effective discharge planning and education.

5. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.
