Adult Health 2 HESI Quizlet
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 father of an 11-year-old client reports to the nurse that the client has been wetting the bed since the passing of his mother and is concerned. Which action is most important for the nurse to take?
- A. Reassure the father that it is normal for a pre-teen to wet the bed during times of stress
- B. Inform the father that nocturnal emissions are abnormal and his son is developmentally delayed
- C. Inform the father that it is most important to let the son know that bedwetting is normal after trauma
- D. Refer the father and the client to a psychologist
Correct answer: D
Rationale: It is common for children to experience bedwetting as a response to severe trauma, such as losing a parent. Referring the father and the client to a psychologist is crucial in this situation to help the child cope with the loss and address any underlying emotional issues. Choice A is incorrect as bedwetting in this context is likely related to the trauma rather than puberty. Choice B is incorrect as nocturnal emissions are not abnormal and do not relate to bedwetting. Choice C is incorrect because the focus should be on addressing the emotional impact of the trauma rather than specifically discussing bedwetting.
3. A patient is receiving a 3% saline continuous IV infusion for hyponatremia. Which assessment data will require the most rapid response by the nurse?
- A. The patient’s radial pulse is 105 beats/minute.
- B. There is sediment and blood in the patient’s urine.
- C. The blood pressure increases from 120/80 to 142/94.
- D. There are crackles audible throughout both lung fields.
Correct answer: D
Rationale: Crackles throughout both lungs suggest that the patient may be experiencing pulmonary edema, a life-threatening adverse effect of hypertonic solutions. The increased pulse rate and blood pressure and the presence of sediment and blood in the urine should also be reported, but they are not as immediately dangerous as the presence of fluid in the alveoli, which compromises gas exchange and can lead to respiratory failure.
4. A patient who has been receiving diuretic therapy is admitted to the emergency department with a serum potassium level of 3.0 mEq/L. The nurse should alert the healthcare provider immediately that the patient is on which medication?
- A. Oral digoxin (Lanoxin) 0.25 mg daily
- B. Ibuprofen (Motrin) 400 mg every 6 hours
- C. Metoprolol (Lopressor) 12.5 mg orally daily
- D. Lantus insulin 24 U subcutaneously every evening
Correct answer: A
Rationale: The correct answer is A. Hypokalemia increases the risk for digoxin toxicity, which can lead to serious dysrhythmias. Therefore, with a low potassium level, the nurse should immediately alert the healthcare provider about the patient being on oral digoxin. Choices B, C, and D do not pose as much concern with the given potassium level. However, further assessment is still required for these medications.
5. 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.
