Nursing Elites

1. Teaching about the need to avoid foods high in potassium is most important for which client?

• A. a client receiving diuretic therapy
• B. a client with an ileostomy
• C. a client with metabolic alkalosis
• D. a client with renal disease

Correct answer: D

Rationale: Clients with renal disease are predisposed to hyperkalemia and should avoid foods high in potassium. High potassium levels can further burden the kidneys and worsen the condition. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk for hypokalemia, which is low potassium levels. Therefore, these clients should actually be encouraged to eat foods high in potassium to maintain adequate levels and prevent complications associated with hypokalemia.

2. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

3. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?

• A. Aspirin
• B. Diazoxide
• C. Procardia
• D. Mannitol

Correct answer: C

Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.

4. Which of the following is an inappropriate item to include in planning care for a severely neutropenic client?

• A. Transfuse neutrophils (granulocytes) to prevent infection.
• B. Exclude raw vegetables from the diet.
• C. Avoid administering rectal suppositories.
• D. Prohibit vases of fresh flowers and plants in the client's room.

Correct answer: A

Rationale: The correct answer is to transfuse neutrophils (granulocytes) to prevent infection. Granulocyte transfusion is not routinely indicated to prevent infection in neutropenic clients. While neutrophils are essential in fighting infections and are beneficial in selected populations of infected, severely granulocytopenic clients who do not respond to antibiotics and are expected to experience prolonged suppression of granulocyte production, routine granulocyte transfusion is not recommended. Choices B, C, and D are appropriate interventions for a severely neutropenic client. Prohibiting fresh flowers and plants helps reduce the risk of exposure to environmental pathogens. Avoiding rectal suppositories minimizes the risk of introducing harmful bacteria. Excluding raw vegetables from the diet reduces the likelihood of foodborne infections.

5. A nurse working in a pediatric clinic observes the following situations. Which of the following may indicate a delayed child to the nurse?

• A. A 12-month-old that does not 'cruise'.
• B. An 8-month-old that can sit upright unsupported.
• C. A 6-month-old that is rolling prone to supine.
• D. A 3-month-old that does not roll supine to prone.

Correct answer: A

Rationale: The correct answer is 'A 12-month-old that does not 'cruise''. At 12 months, a child should at least be 'cruising' (holding on to objects to walk), which is considered pre-walking. The other choices describe age-appropriate developmental milestones: sitting upright unsupported by 8 months, rolling prone to supine by 6 months, and rolling supine to prone by 3 months. Not 'cruising' at 12 months may indicate a delay in motor skills development.
