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 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.

3. The nurse is preparing to send a client to the cardiac catheterization lab for an angioplasty. Which client report is most important for the nurse to explore further prior to the procedure?

• A. Experiences facial swelling after eating crab
• B. Reports left chest wall pain prior to the admission
• C. Verbalizes a fear of being in a confined space
• D. Drank a glass of water

Correct answer: A

Rationale: The correct answer is A. Allergy to shellfish can indicate a potential allergy to iodine, which is used in contrast dye for the procedure. This must be explored further to prevent an allergic reaction. Choice B is not directly related to the angioplasty procedure. Choice C pertains to claustrophobia, which can be addressed but is not directly related to the safety of the procedure. Choice D is a routine activity and does not pose a risk to the client during the procedure.

4. A postoperative client has three different PRN analgesics prescribed for different levels of pain. The nurse inadvertently administers a dose that is not within the prescribed parameters. What actions should the nurse take first?

• A. Assess for side effects of the medication.
• B. Document the client's responses.
• C. Complete a medication error report.
• D. Determine if the pain was relieved.

Correct answer: A

Rationale: This is a medication error, and the first step in addressing it is to assess for any side effects of the medication on the patient. Some analgesics can cause respiratory depression, so it is crucial to monitor for vital sign changes or respiratory distress. Once the patient is stable, the next steps would include contacting the provider, documenting the response, and completing a medication error report. Choices B, C, and D are not the immediate priority when dealing with a medication error. While documenting the client's responses and completing a medication error report are important, assessing for side effects and ensuring patient safety come first.

5. 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.
