Nursing Elites

1. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?

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

Correct answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.

2. While changing a client's post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given there is a positive MRSA, which is the most important action for the nurse to take?

• A. Force oral fluids
• B. Request a nutrition consult
• C. Initiate contact precautions
• D. Limit visitors to immediate family only

Correct answer: C

Rationale: The most important action for the nurse to take when a client has a positive MRSA and presents with a wound showing signs of infection is to initiate contact precautions. MRSA is highly contagious and placing the patient on contact precautions helps prevent the spread of the bacteria to others in the healthcare setting. (A) Forcing oral fluids will not directly address the MRSA infection. (B) Requesting a nutrition consult is not the priority in this situation. (D) Limiting visitors to immediate family only is not necessary as MRSA precautions are primarily focused on healthcare workers and close contacts who provide direct care.

3. The father of an 11-year-old client reports to the nurse that the client has been wetting the bed since the passing of his mother and is concerned. Which action is most important for the nurse to take?

• A. Reassure the father that it is normal for a pre-teen to wet the bed during times of stress
• B. Inform the father that nocturnal emissions are abnormal and his son is developmentally delayed
• C. Inform the father that it is most important to let the son know that bedwetting is normal after trauma
• D. Refer the father and the client to a psychologist

Correct answer: D

Rationale: It is common for children to experience bedwetting as a response to severe trauma, such as losing a parent. Referring the father and the client to a psychologist is crucial in this situation to help the child cope with the loss and address any underlying emotional issues. Choice A is incorrect as bedwetting in this context is likely related to the trauma rather than puberty. Choice B is incorrect as nocturnal emissions are not abnormal and do not relate to bedwetting. Choice C is incorrect because the focus should be on addressing the emotional impact of the trauma rather than specifically discussing bedwetting.

4. A patient who had a transverse colectomy for diverticulosis 18 hours ago has nasogastric suction and is complaining of anxiety and incisional pain. The patient’s respiratory rate is 32 breaths/minute and the arterial blood gases (ABGs) indicate respiratory alkalosis. Which action should the nurse take first?

• A. Discontinue the nasogastric suction.
• B. Give the patient the PRN IV morphine sulfate 4 mg.
• C. Notify the health care provider about the ABG results.
• D. Teach the patient how to take slow, deep breaths when anxious.

Correct answer: B

Rationale: The patient’s respiratory alkalosis is caused by the increased respiratory rate associated with pain and anxiety. The nurse’s first action should be to medicate the patient for pain. Although the nasogastric suction may contribute to the alkalosis, it is not appropriate to discontinue the tube when the patient needs gastric suction. The health care provider may be notified about the ABGs but is likely to instruct the nurse to medicate for pain. The patient will not be able to take slow, deep breaths when experiencing pain.

5. A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient complains of "just blowing up" and has peripheral edema and shortness of breath. Which assessment should the nurse complete first?

• A. Skin turgor
• B. Heart sounds
• C. Mental status
• D. Capillary refill

Correct answer: C

Rationale: Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds also may be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.
