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. After an endotracheal tube is placed in a client who experienced sudden onset of respiratory distress, what should the nurse do?

• A. Secure the tube in place with tape
• B. Order a chest x-ray for the client
• C. Document the depth of tube insertion
• D. Auscultate both lungs for breath sounds

Correct answer: D

Rationale: After endotracheal tube insertion, the nurse should auscultate both lungs for the presence of breath sounds. This step helps confirm proper tube placement and adequate ventilation. Auscultation of breath sounds is crucial to ensure that the tube is correctly positioned in the trachea and not in the esophagus. While securing the tube with tape is important, it is not the immediate priority after insertion. Ordering a chest x-ray may be necessary but is not the first action to take immediately post-intubation. Documenting the depth of tube insertion is important but ensuring proper ventilation through auscultation takes precedence.

3. When assessing an individual with peripheral vascular disease, which clinical manifestation would indicate complete arterial obstruction in the lower left leg?

• A. Aching pain in the left calf.
• B. Burning pain in the left calf.
• C. Numbness and tingling in the left leg.
• D. Coldness of the left foot and ankle.

Correct answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

4. The healthcare provider is assessing a client who is receiving hemodialysis for the first time. Which of the following findings should be reported to the healthcare provider immediately?

• A. Blood pressure of 150/90 mm Hg.
• B. Nausea and vomiting.
• C. Fatigue.
• D. Headache.

Correct answer: B

Rationale: Nausea and vomiting are critical symptoms that should be reported immediately when a client is receiving hemodialysis for the first time. These symptoms could indicate a severe complication, such as hypotension, infection, electrolyte imbalance, or other adverse reactions to the procedure. It is essential to address these symptoms promptly to prevent further complications or harm to the client. Choices A, C, and D are not immediate concerns during the first hemodialysis session and can be addressed appropriately after addressing the urgent issue of nausea and vomiting.

5. Which of the following is a sign of hypocalcemia?

• A. Hyperactive reflexes.
• B. Depressed reflexes.
• C. Muscle cramps.
• D. Seizures.

Correct answer: A

Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.
