Nursing Elites

1. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

2. A patient with leukemia is receiving chemotherapy that is known to depress bone marrow. A CBC (complete blood count) reveals a platelet count of 25,000/microliter. Which of the following actions related specifically to the platelet count should be included in the nursing care plan?

• A. Monitor for fever every 4 hours.
• B. Require visitors to wear respiratory masks and protective clothing.
• C. Consider transfusion of packed red blood cells.
• D. Check for signs of bleeding, including examination of urine and stool for blood.

Correct answer: D

Rationale: A platelet count of 25,000/microliter indicates severe thrombocytopenia, which increases the risk of bleeding. It is crucial to initiate bleeding precautions, including regularly checking for signs of bleeding such as examining urine and stool for blood. Monitoring for fever every 4 hours (Choice A) should be included for neutropenic precautions, not specifically related to platelet count. Requiring visitors to wear respiratory masks and protective clothing (Choice B) is more relevant for patients with airborne precautions. Considering transfusion of packed red blood cells (Choice C) is not indicated for low platelet count but is more appropriate for managing anemia or low hemoglobin levels.

3. A client with Multiple Sclerosis reports a constant, burning, tingling pain in the shoulders. The nurse anticipates that the physician will order which medication for this type of pain?

• A. alprazolam (Xanax)
• B. Corticosteroid injection
• C. gabapentin (Neurontin)
• D. hydrocodone/acetaminophen (Norco)

Correct answer: C

Rationale: For neuropathic pain associated with conditions like Multiple Sclerosis, medications like gabapentin, an anticonvulsant, are commonly used. Gabapentin helps in managing nerve pain by stabilizing electrical activity in the brain and nervous system. Alprazolam is a benzodiazepine used for anxiety and not primarily indicated for neuropathic pain. Corticosteroid injections are more suitable for inflammatory conditions like arthritis, not for neuropathic pain. Hydrocodone/acetaminophen is an opioid combination used for moderate to severe pain, but it is not the first-line choice for neuropathic pain.

4. To palpate the liver during a head-to-toe physical assessment, the nurse should

• A. put pressure on the biopsy site using a sandbag
• B. elevate the head of the bed to facilitate breathing
• C. place the patient on the right side with the bed flat
• D. check the patient's post-biopsy coagulation studies

Correct answer: C

Rationale: To palpate the liver effectively during a head-to-toe physical assessment, the patient should be positioned on the right side with the bed flat. This position helps to splint the biopsy site and allows for proper palpation of the liver. Elevating the head of the bed has no direct relevance to palpating the liver. Checking coagulation studies is done before the biopsy and is unrelated to palpation. Putting pressure on the biopsy site using a sandbag is not an appropriate way to facilitate liver palpation as it does not provide the necessary support and stabilization needed for the procedure.

5. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
