Nursing Elites

1. Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?

• A. Neutrophils
• B. Lymphocytes
• C. Eosinophils
• D. Monocytes

Correct answer: C

Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (Choice A) are mainly involved in fighting bacterial infections. Lymphocytes (Choice B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (Choice D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.

2. A client in the intensive care unit is being mechanically ventilated, has an indwelling urinary catheter in place, and is exhibiting signs of restlessness. Which action should the nurse take first?

• A. Review the heart rhythm on cardiac monitors
• B. Check urinary catheter for obstruction
• C. Auscultate bilateral breath sounds
• D. Give PRN dose of lorazepam (Ativan)

Correct answer: B

Rationale: When a client in the intensive care unit is mechanically ventilated, has an indwelling urinary catheter, and is restless, the priority action is to check the urinary catheter for obstruction. Restlessness in this context could be due to a blocked catheter causing discomfort or urinary retention, which needs immediate attention to prevent complications. Reviewing the heart rhythm on cardiac monitors can be important but is not the priority in this scenario. Auscultating bilateral breath sounds is also important in a ventilated client but addressing the potential immediate issue of a blocked catheter takes precedence. Giving a PRN dose of lorazepam should not be the first action without addressing the underlying cause of restlessness.

3. A client with osteoporosis related to long-term corticosteroid therapy receives a prescription for calcium carbonate. Which client’s serum laboratory value requires intervention by the nurse?

• A. Total calcium 9 mg/dl (2.25 mmol/L SI)
• B. Creatinine 4 mg/dl (354 micromol/L SI)
• C. Phosphate 4 mg/dl (1.293 mmol/L SI)
• D. Fasting glucose 95 mg/dl (5.3 mmol/L SI)

Correct answer: B

Rationale: An elevated creatinine level indicates possible renal impairment, which requires intervention. High creatinine levels are associated with decreased kidney function, and in this case, it suggests potential renal issues due to long-term corticosteroid therapy. Monitoring renal function is crucial in clients with osteoporosis on corticosteroid therapy to prevent further complications. Total calcium levels within the normal range are suitable for a client with osteoporosis receiving calcium carbonate. Phosphate and fasting glucose levels do not directly indicate renal impairment in this scenario.

4. A client is admitted with pyelonephritis, and cultures reveal an Escherichia coli infection. The client is allergic to penicillins, and the healthcare provider prescribed vancomycin IV. The nurse should plan to carefully monitor the client for which finding during IV administration?

• A. Tissue sloughing upon extravasation
• B. Elevated blood pressure and heart rate
• C. Tinnitus and vertigo
• D. Erythema of the face, neck, and chest

Correct answer: C

Rationale: The correct answer is C: Tinnitus and vertigo. Vancomycin can cause ototoxicity and nephrotoxicity, leading to symptoms like tinnitus and vertigo. Monitoring for these adverse effects is crucial to prevent further complications. Choices A, B, and D are incorrect because tissue sloughing, elevated blood pressure and heart rate, and erythema of the face, neck, and chest are not typically associated with vancomycin administration. Therefore, the nurse should focus on monitoring for signs of ototoxicity and nephrotoxicity such as tinnitus and vertigo.

5. When educating a group of school-age children on reducing the risk of Lyme disease, which instruction should the camp nurse include?

• A. Wash hands frequently
• B. Avoid drinking lake water
• C. Wear long sleeves and pants
• D. Do not share personal products

Correct answer: C

Rationale: The correct instruction to reduce the risk of Lyme disease is to wear long sleeves and pants. This helps prevent tick bites, which are the primary mode of transmission for Lyme disease. Wearing protective clothing reduces the skin's exposure to ticks, decreasing the chances of getting bitten. Washing hands frequently (Choice A) is important for general hygiene but not specifically for preventing Lyme disease. Avoiding drinking lake water (Choice B) is unrelated to the prevention of Lyme disease. Not sharing personal products (Choice D) is important for preventing the spread of infections but does not directly reduce the risk of Lyme disease.
