1. While assessing a patient in the ICU, a nurse observes signs of a weak pulse, quick respiration, acetone breath, and nausea. Which of the following conditions is most likely occurring?
- A. Hypoglycemic patient
- B. Hyperglycemic patient
- C. Cardiac arrest
- D. End-stage renal failure
Correct answer: B
Rationale: The correct answer is a hyperglycemic patient. The signs described - weak pulse, quick respiration, acetone breath, and nausea - are indicative of hyperglycemia. A hypoglycemic patient would typically present with different signs such as pale skin, sweating, and confusion. Cardiac arrest would manifest with sudden loss of heart function and consciousness, not the signs described. End-stage renal failure would present with symptoms related to kidney dysfunction like edema, fatigue, and changes in urine output, which are not mentioned in the scenario.
2. A nurse suspects a patient is developing Bell's Palsy. The nurse wants to test the function of cranial nerve VII. Which of the following would be the most appropriate testing procedures?
- A. Test the taste sensation over the back of the tongue and activation of the facial muscles.
- B. Test the taste sensation over the front of the tongue and activation of the facial muscles.
- C. Test the sensation of the facial muscles and sensation of the back of the tongue.
- D. Test the sensation of the facial muscles and sensation of the front of the tongue.
Correct answer: B
Rationale: The facial nerve (VII) is responsible for motor function to the face and sensory function to the anterior two-thirds of the tongue. Therefore, to appropriately test the function of cranial nerve VII, the most appropriate testing procedures involve assessing the taste sensation over the front of the tongue (sensory) and activation of the facial muscles (motor). Option B, 'Test the taste sensation over the front of the tongue and activation of the facial muscles,' is the correct answer. Choices A, C, and D are incorrect because they do not involve the correct combination of sensory testing over the front of the tongue and motor activation of the facial muscles, which are key functions associated with cranial nerve VII.
3. The nurse is caring for a burn victim with a skin graft to the hand. The area is pale and mottled but has good capillary refill. What is the nurse's best action at this time?
- A. Warm the room
- B. Submerge the hand in warm water
- C. Order a K pad and apply to hand
- D. Have the client exercise the fingers to increase blood flow
Correct answer: A
Rationale: The correct action for the nurse to take when caring for a burn victim with a skin graft to the hand, exhibiting pale and mottled skin but good capillary refill, is to warm the room. By warming the room, the nurse helps promote circulation and maintain a conducive environment for healing. Submerging the hand in warm water can pose a risk of injury or infection to the graft site. Ordering a K pad and applying it to the hand may not be necessary at this time and could potentially cause harm. Having the client exercise the fingers to increase blood flow is also not recommended as it may interfere with the healing process of the skin graft.
4. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: B
Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.
5. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?
- A. tuberculosis (TB)
- B. pneumonia
- C. pleural effusion
- D. hypoxia
Correct answer: D
Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.
