Nursing Elites

1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?

• A. Contractures.
• B. Constipation.
• C. Calcium loss.
• D. Catabolism.

Correct answer: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

3. Which of the following nursing interventions is appropriate for a client suffering from a fever?

• A. Avoid withholding food from the client
• B. Increase the client's fluid intake
• C. Provide oxygen
• D. All answers are correct

Correct answer: B

Rationale: The appropriate nursing intervention for a client suffering from a fever is to increase the client's fluid intake. A fever can elevate the body's metabolism, leading to increased breathing and heart workload. This can result in fluid loss due to heightened respiration and sweating. Moreover, the augmented heart workload may necessitate more oxygen to maintain tissue perfusion. Providing oxygen and increasing fluid intake help meet the body's heightened demands during a fever. Withholding food from the client is inappropriate as proper nutrition is crucial for recovery, and providing oxygen alone may not address the fluid and metabolic demands associated with fever. Therefore, the correct choice is to increase the client's fluid intake.

4. A client is refusing to undergo any more treatments in the hospital and wants to leave against medical advice. When the nurse requests the client to sign an AMA order, the client refuses and leaves. What is the next action of the nurse?

• A. Call security to hold the client until he signs the order
• B. Notify the physician to convince the client to stay
• C. Speak with the client's spouse to persuade him to stay
• D. Allow the client to leave and document the refusal in his chart

Correct answer: D

Rationale: The nurse cannot force the client to stay in the hospital to receive treatment or to sign an AMA order. It is essential to respect the client's autonomy and decision-making capacity. While involving security or pressuring the client through the physician or spouse may seem like options, they are not appropriate in this situation. The nurse should allow the client to leave if they are competent to make that decision, document the refusal in the client's chart to ensure all actions are appropriately documented, and follow institutional policies for patients leaving against medical advice.

5. 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.
