1. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: D
Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.
2. The home health nurse cares for an alert and oriented older adult patient with a history of dehydration. Which instructions should the nurse give to this patient related to fluid intake?
- A. Increase fluids if your mouth feels dry.
- B. More fluids are needed if you feel thirsty.
- C. Drink more fluids in the late evening hours.
- D. If you feel lethargic or confused, you need more to drink.
Correct answer: A
Rationale: The correct answer is A. An alert, older patient can self-assess for signs of dehydration like dry mouth. This instruction is appropriate as it encourages the patient to respond to early signs of dehydration. Choice B is incorrect because the thirst mechanism decreases with age and feeling thirsty may not accurately indicate the need for fluids. Choice C is incorrect as many older patients prefer to limit evening fluid intake to enhance sleep quality. Choice D is incorrect because an older adult who is lethargic or confused may not be able to accurately assess their need for fluids.
3. The nurse assesses a client who has a nasal cannula delivering oxygen at 2 L/min. To assess for skin damage related to the cannula, which areas should the nurse observe? (Select all that apply).
- A. Tops of the ears
- B. Bridge of the nose
- C. Around the nostrils
- D. Over the cheeks
Correct answer: C
Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.
4. The long-term care nurse is evaluating the effectiveness of protein supplements for an older resident who has a low serum total protein level. Which assessment finding indicates that the patient’s condition has improved?
- A. Hematocrit 28%
- B. Absence of skin tenting
- C. Decreased peripheral edema
- D. Blood pressure 110/72 mm Hg
Correct answer: C
Rationale: The decrease in peripheral edema indicates an improvement in the patient’s protein status. Edema is caused by low oncotic pressure in individuals with low serum protein levels. Good skin turgor is an indicator of fluid balance, not protein status. A low hematocrit could be caused by poor protein intake. Blood pressure does not provide a useful clinical tool for monitoring protein status.
5. A patient who had a transverse colectomy for diverticulosis 18 hours ago has nasogastric suction and is complaining of anxiety and incisional pain. The patient’s respiratory rate is 32 breaths/minute and the arterial blood gases (ABGs) indicate respiratory alkalosis. Which action should the nurse take first?
- A. Discontinue the nasogastric suction.
- B. Give the patient the PRN IV morphine sulfate 4 mg.
- C. Notify the health care provider about the ABG results.
- D. Teach the patient how to take slow, deep breaths when anxious.
Correct answer: B
Rationale: The patient’s respiratory alkalosis is caused by the increased respiratory rate associated with pain and anxiety. The nurse’s first action should be to medicate the patient for pain. Although the nasogastric suction may contribute to the alkalosis, it is not appropriate to discontinue the tube when the patient needs gastric suction. The health care provider may be notified about the ABGs but is likely to instruct the nurse to medicate for pain. The patient will not be able to take slow, deep breaths when experiencing pain.
