Medical Surgical Assignment Exam HESI
1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?
- A. The client is hyperventilating due to anxiety.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client is experiencing respiratory alkalosis.
- D. The client is experiencing metabolic acidosis.
Correct answer: B
Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.
2. In the change of shift report, the nurse is told that a client has a stage 2 pressure ulcer. Which ulcer appearance is most likely to be observed?
- A. Shallow open ulcer with a red-pink wound bed.
- B. Intact skin with non-blanchable redness.
- C. Full-thickness tissue loss with visible fat.
- D. Full-thickness tissue loss with exposed bone, tendon, or muscle.
Correct answer: A
Rationale: The correct answer is A: 'Shallow open ulcer with a red-pink wound bed.' Stage 2 pressure ulcers involve partial-thickness skin loss and typically appear as shallow open ulcers with a red-pink wound bed. Choice B describes a stage 1 ulcer, where the skin is intact but shows non-blanchable redness. Choice C describes a stage 3 ulcer, with full-thickness tissue loss exposing fat. Choice D is characteristic of a stage 4 ulcer, where there is full-thickness tissue loss exposing bone, tendon, or muscle. Therefore, option A best fits the description of a stage 2 pressure ulcer.
3. A postoperative client reports incisional pain. The client has two prescriptions for PRN analgesia that accompanied the client from the post-anesthesia unit. Before selecting which medication to administer, which action should the nurse implement?
- A. Document the client's report of pain in the electronic medical record.
- B. Determine which prescription will have the quickest onset of action.
- C. Compare the client's pain scale rating with the prescribed dosing.
- D. Ask the client to choose which medication is needed for the pain.
Correct answer: C
Rationale: The correct action the nurse should implement before selecting which medication to administer to a postoperative client who reports incisional pain is to compare the client's pain scale rating with the prescribed dosing. This ensures that the client receives the appropriate medication based on their pain level. Documenting the client's report of pain in the electronic medical record (Choice A) is important but should come after ensuring the right medication is given. Determining which prescription will have the quickest onset of action (Choice B) may not be the most relevant factor to consider when choosing the appropriate medication. Asking the client to choose the medication needed for the pain (Choice D) may not be appropriate as the nurse should rely on the pain scale rating and prescribed dosing to make a clinical decision.
4. The nurse is triaging clients who have been injured during a tornado. Which client requires immediate action?
- A. A young male with a minor laceration on his forearm.
- B. An elderly woman with a dislocated shoulder who is calm.
- C. A middle-aged female with a broken humerus who is unable to follow commands and is crying.
- D. A teenager with abrasions and a bruised knee.
Correct answer: C
Rationale: The middle-aged female with a broken humerus who is unable to follow commands and is crying requires immediate action. These symptoms indicate a possible head injury or severe emotional distress that need urgent attention. Choice A is not as urgent since a minor laceration can be addressed after more critical cases. Choice B, although having a dislocated shoulder, is stable, as the client is calm. Choice D presents with minor injuries that can wait while more critical cases are addressed.
5. What is the most common clinical manifestation of coarctation of the aorta?
- A. Clubbing of the digits
- B. Upper extremity hypertension
- C. Pedal edema and portal congestion
- D. Loud systolic ejection murmur
Correct answer: B
Rationale: The correct answer is B: Upper extremity hypertension. Coarctation of the aorta leads to increased blood pressure in the upper extremities. The pressure in the arms is typically 20 mm Hg higher than in the legs. Choice A, clubbing of the digits, is not a common clinical manifestation of coarctation of the aorta. Choice C, pedal edema, and portal congestion are more suggestive of conditions like heart failure rather than coarctation of the aorta. Choice D, loud systolic ejection murmur, can be heard in conditions like aortic stenosis, but it is not the most common clinical manifestation of coarctation of the aorta.
