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. 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.

3. A patient is receiving a 3% saline continuous IV infusion for hyponatremia. Which assessment data will require the most rapid response by the nurse?

• A. The patient’s radial pulse is 105 beats/minute.
• B. There is sediment and blood in the patient’s urine.
• C. The blood pressure increases from 120/80 to 142/94.
• D. There are crackles audible throughout both lung fields.

Correct answer: D

Rationale: Crackles throughout both lungs suggest that the patient may be experiencing pulmonary edema, a life-threatening adverse effect of hypertonic solutions. The increased pulse rate and blood pressure and the presence of sediment and blood in the urine should also be reported, but they are not as immediately dangerous as the presence of fluid in the alveoli, which compromises gas exchange and can lead to respiratory failure.

4. The nurse observes an unlicensed assistive personnel (UAP) who is providing a total bed bath for a confused and lethargic client. The UAP is soaking the client's foot in a basin of warm water placed on the bed. What action should the nurse take?

• A. Remove the basin of water from the client's bed immediately
• B. Remind the UAP to dry between the client's toes completely
• C. Advise the UAP that this procedure is damaging to the skin
• D. Add skin cream to the basin of water while the foot is soaking

Correct answer: B

Rationale: Choice (B) is the correct action for the nurse to take in this situation. Ensuring that the UAP dries between the client's toes completely is crucial to prevent skin breakdown due to excessive moisture. While keeping the client's feet clean is important, maintaining dryness is paramount for skin integrity. Choices (A), (C), and (D) are incorrect: (A) removing the basin of water immediately may disrupt the care process without addressing the root issue, (C) advising the UAP that the procedure is damaging to the skin is not as immediate or specific to the observed problem, and (D) adding skin cream to the water may not address the need for drying the client's toes thoroughly.

5. A male client with unstable angina needs a cardiac catheterization. So the healthcare provider explains the risks and benefits of the procedure and then leaves to set up for the procedure. When the nurse presents the consent form for signature, the client hesitates and asks how the wires will keep his heart going. Which action should the nurse take?

• A. Answer the client's specific questions with a short, understandable explanation
• B. Postpone the procedure until the client understands the risks and benefits
• C. Call the client's next of kin and ask them to provide verbal consent
• D. Page the healthcare provider to return and provide additional explanation

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to page the healthcare provider to return and provide additional explanation. It is crucial for the client to have a clear understanding of the procedure, including its risks and benefits, before signing the consent form. While the nurse can provide general information, the detailed explanation of how the procedure works and its effects should come from the healthcare provider who will perform the procedure. Postponing the procedure until the client understands is appropriate, but the immediate need is to clarify the client's concerns with the healthcare provider. Calling the client's next of kin for verbal consent is not the correct course of action as the client is present and able to provide consent after receiving adequate information.
