ATI Fundamentals

1. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

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

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

2. A client experiencing acute dyspnea and diaphoresis reports anxiety and difficulty breathing. Vital signs include HR 117/min, respirations 38/min, temperature 38.4 C (101.2 F), and blood pressure 100/54 mm Hg. What should the nurse prioritize?

A. Notify the provider.
B. Administer heparin via IV infusion.
C. Administer oxygen therapy.
D. Obtain a spiral CT scan.

Correct answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.

3. When discussing hair loss with Mrs. Lim, who begins to cry, the best response would be:

A. Don’t worry. It’s only temporary
B. Why are you crying? I didn’t get to the bad news yet
C. Your hair is really pretty
D. I know this will be difficult for you, but your hair will grow back after the completion of chemotherapy

Correct answer: D

Rationale: When a patient is emotionally affected, it is essential to acknowledge their feelings while providing reassurance and information. Option D demonstrates empathy by acknowledging the difficulty Mrs. Lim is facing and offers hope by reassuring her that her hair will grow back after chemotherapy, which can provide comfort and support during a challenging time.

4. Which of the following scenarios represents nursing malpractice?

A. The nurse administers penicillin to a patient with a documented history of allergy to the drug. The patient experiences an allergic reaction and suffers cerebral damage due to anoxia.
B. The nurse applies a hot water bottle or a heating pad to the abdomen of a patient with abdominal cramping.
C. The nurse assists a patient out of bed with the bed locked in position; the patient slips and fractures his right humerus.
D. The nurse administers the wrong medication to a patient, resulting in vomiting. This error is documented and reported to the physician and the nursing supervisor.

Correct answer: A

Rationale: The correct answer is A. Administering a drug to a patient with a known allergy, leading to severe harm such as an allergic reaction causing cerebral damage due to anoxia, constitutes nursing malpractice. In this scenario, the nurse failed to adhere to the standard of care by administering a medication that the patient was allergic to, resulting in serious harm, which is a clear example of malpractice in nursing.

5. Which of the following procedures always requires surgical asepsis?

A. Vaginal instillation of conjugated estrogen
B. Urinary catheterization
C. Nasogastric tube insertion
D. Colostomy irrigation

Correct answer: B

Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.
