A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct Answer: A
Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.

A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor while the patient is receiving this infusion?
- A. Lung sounds
- B. Urinary output
- C. Peripheral pulses
- D. Peripheral edema
Correct Answer: A
Rationale: The correct answer is A: Lung sounds. Hypertonic solutions like 3% NaCl can cause water retention, leading to fluid excess. Monitoring lung sounds is crucial as crackles may indicate pulmonary edema, a serious manifestation of fluid excess. While monitoring urinary output, peripheral pulses, and peripheral edema are also important when administering hypertonic solutions, they do not provide immediate clues to acute respiratory or cardiac decompensation like lung sounds.
The nurse notes a serum calcium level of 7.9 mg/dL for a patient who has chronic malnutrition. Which action should the nurse take next?
- A. Monitor ionized calcium level.
- B. Give oral calcium citrate tablets.
- C. Check parathyroid hormone level.
- D. Administer vitamin D supplements.
Correct Answer: A
Rationale: This patient with chronic malnutrition is likely to have a low serum albumin level, which will affect the total serum calcium. A more accurate reflection of calcium balance is the ionized calcium level. Most of the calcium in the blood is bound to protein (primarily albumin). Alterations in serum albumin levels affect the interpretation of total calcium levels. Low albumin levels result in a drop in the total calcium level, although the level of ionized calcium is not affected. The nurse should monitor the ionized calcium level to get a clearer picture of the patient's calcium status. Giving oral calcium citrate tablets, checking parathyroid hormone level, or administering vitamin D supplements may be necessary based on the ionized calcium results, but they are not the immediate next step in assessment and management.
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.
The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate?
- A. Avoid using friction when cleaning around the CVAD insertion site.
- B. Use the push-pause method to flush the CVAD after giving medications.
- C. Obtain an order from the healthcare provider to change the CVAD dressing.
- D. Position the patient's face away from the CVAD during injection cap changes.
Correct Answer: B
Rationale: The correct answer is B because using the push-pause method to flush the CVAD after giving medications helps remove debris from the CVAD lumen and decreases the risk for clotting. Choice A is incorrect because friction should be used when cleaning the CVAD insertion site to decrease infection risk. Choice C is incorrect because obtaining an order from the healthcare provider to change the CVAD dressing is not necessary; the dressing should be changed when damp, loose, or visibly soiled. Choice D is incorrect because the patient should face away from the CVAD during cap changes to minimize the risk of contamination.
A client who has a body mass index (BMI) of 30 is requesting information on the initial approach to a weight loss plan. Which action should the nurse recommend first?
- A. Plan low-carbohydrate and high-protein meals
- B. Engage in moderate physical activity for an hour daily
- C. Keep a record of food and drinks consumed daily
- D. Participate in a group exercise class 3 times a week
Correct Answer: C
Rationale: A BMI of 30 indicates the patient is obese. The first step in a weight loss plan should be to keep a food journal to track calorie intake, which can help in meal planning and creating a workout routine. Choice (A) suggests a dietary approach, which is important but not the first step. Choice (B) recommends strenuous activity, which may not be suitable for everyone and is not the initial step. Choice (D) involves group exercise, which can be beneficial but is not the primary action to take at the beginning of a weight loss plan.
