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 older patient receiving iso-osmolar continuous tube feedings develops restlessness, agitation, and weakness. Which laboratory result should the nurse report to the health care provider immediately?

• A. K+ 3.4 mEq/L (3.4 mmol/L)
• B. Ca+2 7.8 mg/dL (1.95 mmol/L)
• C. Na+ 154 mEq/L (154 mmol/L)
• D. PO4-3 4.8 mg/dL (1.55 mmol/L)

Correct answer: C

Rationale: The correct answer is C. The elevated serum sodium level (154 mEq/L) is consistent with the patient's neurologic symptoms of restlessness, agitation, and weakness, indicating a need for immediate action to prevent complications like seizures. The potassium level (3.4 mEq/L) and calcium level (7.8 mg/dL) are slightly off from normal but do not require immediate action. The phosphate level (4.8 mg/dL) is normal and not related to the symptoms presented by the patient.

3. The nurse is teaching the parent of a child newly diagnosed with a latex allergy. Which information by the parents indicates a need for further teaching?

• A. Rubber-free toys, such as wooden building blocks, are good choices for the child.
• B. Only foil balloons will be used for the child's birthday party.
• C. A diet of healthy fruits, such as bananas and kiwis, is best for the child.
• D. An epinephrine auto-injector will be on hand to treat allergic reactions.

Correct answer: C

Rationale: The correct answer is C. Bananas and kiwis are foods that can cross-react with latex allergy, indicating that the parents need further teaching on managing latex allergies. Choices A, B, and D are correct as rubber-free toys, using foil balloons, and having an epinephrine auto-injector are appropriate measures to prevent and manage allergic reactions in a child with a latex allergy.

4. A 54-year-old male client and his wife were informed this morning that he has terminal cancer. Which nursing intervention is likely to be most beneficial?

• A. Ask the wife how she would like to participate in the client's care
• B. Provide the wife with information about hospice
• C. Encourage the wife to visit after painful treatments are completed
• D. Refer the wife to a support group for family members of those dying of cancer

Correct answer: A

Rationale: The most beneficial nursing intervention in this situation is to ask the wife how she would like to participate in the client's care. Involving the spouse in the care of the terminally ill client can provide comfort, support, and a sense of contribution during a challenging time. Providing information about hospice (B) is important but may not be the immediate priority. Encouraging the wife to visit after treatments are completed (C) may delay her involvement in the care. Referring her to a support group (D) is a good idea but might be more suitable at a later stage.

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.
