Nursing Elites

1. Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:

• A. the client's hemoglobin and hematocrit are normal.
• B. red blood cells are affected first.
• C. folic acid levels are normal.
• D. the current white cell count is not affected by chemotherapy.

Correct answer: D

Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy. Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.

2. Which of the following is not typically considered one of the main mechanisms of Type II Diabetes treatment?

• A. Medications
• B. Nutrition
• C. Increased activity
• D. Continuous Insulin

Correct answer: D

Rationale: Continuous Insulin is not typically considered one of the main mechanisms for treating Type II Diabetes. While medications, nutrition, and increased activity play crucial roles in managing Type II Diabetes, continuous insulin therapy is more common in Type I Diabetes or in specific cases of Type II Diabetes where other treatments are ineffective. Therefore, the correct answer is Continuous Insulin. Choices A, B, and C are mainstays in the treatment of Type II Diabetes, making them incorrect answers.

3. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

4. Which infection control measure is the priority for the nurse to implement in the care provided for a child admitted to the hospital with bacterial meningitis?

• A. Place the child in a private room
• B. Gowns and masks must be worn by all personnel in the child's room
• C. Visitors are restricted to parents only
• D. Hand washing is required by all personnel and visitors having contact with the child

Correct answer: B

Rationale: The priority control measure for the nurse to implement in caring for a child with bacterial meningitis is ensuring that gowns and masks are worn by all personnel in the child's room. This measure is crucial as the child with bacterial meningitis is contagious for at least 24 hours after starting antibiotics, necessitating airborne precautions to prevent the spread of infection to healthcare workers and other patients. Placing the child in a private room (Choice A) is important but secondary to preventing infection transmission. Restricting visitors to parents only (Choice C) is also significant but not as critical as ensuring proper infection control measures. While hand washing (Choice D) is essential, the immediate need to prevent airborne transmission in the child's room takes precedence.

5. When administering intravenous electrolyte solution, what precaution should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for adjustments due to IV calcium.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer. Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects. Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia. Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.
