Nursing Elites

1. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.

2. In assessing cancer risk, which woman is at greatest risk of developing breast cancer?

• A. A 35-year-old multipara who never breastfed.
• B. A 50-year-old whose mother had unilateral breast cancer.
• C. A 55-year-old whose mother-in-law had bilateral breast cancer.
• D. A 20-year-old whose menarche occurred at age 9.

Correct answer: B

Rationale: The correct answer is B because family history of breast cancer, specifically in the mother, is a significant risk factor for developing breast cancer. The age of 50 is also a risk factor for breast cancer. Choice A is less likely as breastfeeding can actually reduce the risk of breast cancer. Choice C is less relevant since the risk is higher with a direct family member. Choice D, although early menarche is a risk factor, the age of the individual is much lower compared to the other age-related risk factors.

3. A client who just returned from the recovery room after a tonsillectomy and adenoidectomy is restless, and her pulse rate is increased. As the nurse continues the assessment, the client begins to vomit a copious amount of bright-red blood. The immediate nursing action is to:

• A. Notify the surgeon
• B. Continue the assessment
• C. Check the client’s blood pressure
• D. Obtain a flashlight, gauze, and a curved hemostat

Correct answer: A

Rationale: In the scenario described, the client's presentation with bright-red blood vomiting after a tonsillectomy and adenoidectomy is highly concerning for an immediate postoperative hemorrhage, which can be life-threatening. The priority action for the nurse is to notify the surgeon immediately. Prompt communication with the surgeon is vital to ensure swift intervention and appropriate management to address the hemorrhage effectively. Continuing the assessment, checking the client's blood pressure, or obtaining equipment are all secondary actions in this critical situation and would delay the necessary urgent intervention required to manage the hemorrhage effectively.

4. The nurse is preparing to administer the first dose of intravenous ceftriaxone (Rocephin) to a patient. When reviewing the patient’s chart, the nurse notes that the patient previously experienced a rash when taking amoxicillin. What is the nurse’s next action?

• A. Administer the drug and observe closely for hypersensitivity reactions.
• B. Ask the provider whether a cephalosporin from a different generation may be used.
• C. Contact the provider to report drug hypersensitivity.
• D. Notify the provider and suggest an oral cephalosporin.

Correct answer: A

Rationale: When a patient has a history of a rash with amoxicillin, a beta-lactam antibiotic like ceftriaxone should be administered cautiously due to a possible cross-reactivity. The nurse should still administer the drug but closely monitor the patient for any signs of hypersensitivity reactions. Asking for a different generation of cephalosporin or suggesting an oral form does not address the potential cross-reactivity issue. Contacting the provider to report drug hypersensitivity would delay care when the patient needs immediate treatment.

5. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?

• A. My sodium level changes due to the movement from the blood into the dialysate.
• B. Dialysis works by the movement of wastes from higher to lower concentration.
• C. Extra fluid can be pulled from the blood by osmosis.
• D. The dialysate is similar to blood but without any toxins.

Correct answer: B

Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.
