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. An adult who has recurrent episodes of depression tells the nurse that the prescribed antidepressant needs to be discontinued because the client is feeling better after taking the medication for the past couple of weeks and does not like the side effects. Which response is best for the nurse to provide?

• A. Remind the client that feeling better is the therapeutic effect of the medication.
• B. Inform the client that gradual tapering must be used to discontinue the medication.
• C. Tell the client to discuss the medication side effects with the healthcare provider.
• D. Tell the client that the medication side effects will most likely diminish over time.

Correct answer: B

Rationale: The best response for the nurse is to inform the client that gradual tapering must be used to discontinue the medication. Abrupt cessation of antidepressants can lead to withdrawal symptoms or a recurrence of depressive symptoms. Choice A is not the best response as it does not address the need for a proper discontinuation plan. Choice C is not the best response as it focuses solely on the side effects and does not address the discontinuation process. Choice D is not the best response because while side effects may diminish over time, the focus here should be on the safe discontinuation of the medication to prevent adverse effects.

3. A female client's significant other has been at her bedside providing reassurances and support for the past 3 days, as desired by the client. The client's estranged husband arrives and demands that the significant other not be allowed to visit or be given condition updates. Which intervention should the nurse implement?

• A. Obtain a court order to enforce visitation rights for the significant other
• B. Request a consultation with the ethics committee for resolution of the situation
• C. Suggest involving security to manage the conflict between the husband and the significant other
• D. Discuss with the client the importance of setting clear boundaries with both individuals

Correct answer: B

Rationale: In this situation, where there is a conflict between the client's significant other and estranged husband, the most appropriate intervention is to request a consultation with the ethics committee for resolution. This ensures that an impartial body can assess the situation, consider the rights and preferences of all parties involved, and provide guidance on how to proceed in a fair and ethical manner. Obtaining a court order (Choice A) may be a legal option but should be considered after exhausting other conflict resolution methods. Involving security (Choice C) may escalate the situation and should only be considered if there is a risk of harm. Discussing boundaries with the client (Choice D) is important but may not immediately address the current conflict between the significant other and the husband.

4. Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?

• A. Tie the knot with a double turn or square knot
• B. Ensure that the restraints are snug against the client's wrists
• C. Ensure that the knot can be quickly released
• D. Move the ties so the restraints are secured to the side rails

Correct answer: C

Rationale: The priority is to ensure that the knot can be quickly released to allow for quick intervention if necessary. Tying the knot with a double turn or square knot (Choice A) may make it more difficult to release quickly in an emergency. Ensuring that the restraints are snug against the client's wrists (Choice B) may compromise circulation and cause discomfort. Moving the ties to secure the restraints to the side rails (Choice D) is not the appropriate action as it can limit the client's movement and access to care.

5. 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.
