Nursing Elites

1. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

2. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

• A. Hypocalcemia.
• B. Hyponatremia.
• C. Hyperkalemia.
• D. Hypophosphatemia.

Correct answer: A.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.

3. When auscultating breath sounds, the nurse auscultates over the following locations:

• A. Trachea and lateral areas of thoracic cage
• B. Anterior and posterior aspects of all lung fields
• C. The mid section as well as the lateral section of the lungs
• D. The mid-clavicular to mid-axillary lines comparing side to side

Correct answer: B

Rationale: The correct answer is B: Anterior and posterior aspects of all lung fields. When auscultating breath sounds, it is essential to listen to the front (anterior) and back (posterior) aspects of all lung fields. This comprehensive approach allows for a thorough assessment of breath sounds throughout the lungs. Choices A, C, and D are incorrect. Choice A is too limited as it only focuses on the trachea and lateral areas, not covering all lung fields. Choice C is also too limited, referring to specific sections of the lungs (mid section and lateral section). Choice D is incorrect as it suggests comparing specific lines on the chest (mid-clavicular to mid-axillary), which is not a standard practice for auscultating breath sounds.

4. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?

• A. Use a soft toothbrush.
• B. Use dental floss daily.
• C. Hold pressure on any scrapes for 1-2 minutes.
• D. Use a triple-edged razor.

Correct answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

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.
