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.

The client with chronic venous insufficiency is being taught about self-care measures. Which instruction should be included?
- A. Avoid wearing compression stockings
- B. Elevate legs above heart level when resting
- C. Apply heat packs to improve circulation
- D. Limit walking to prevent leg pain
Correct Answer: B
Rationale: The correct instruction for a client with chronic venous insufficiency is to elevate their legs above heart level when resting. This position helps reduce venous pressure and edema, improving circulation. Avoiding compression stockings (choice A) is incorrect as they are beneficial in managing chronic venous insufficiency. Applying heat packs (choice C) is not recommended as heat can worsen edema. Limiting walking (choice D) is not advisable as regular, gentle exercise like walking can actually help improve circulation in patients with chronic venous insufficiency.
Which of the following is a priority assessment for a client receiving intravenous vancomycin?
- A. Respiratory rate
- B. Blood pressure
- C. Urine output
- D. Hearing acuity
Correct Answer: D
Rationale: The correct answer is D, Hearing acuity. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Monitoring the client's hearing acuity is crucial to detect any early signs of ototoxicity. Assessing respiratory rate, blood pressure, and urine output are important assessments in general patient care but are not the priority when specifically monitoring for vancomycin-induced ototoxicity.
The nurse is reviewing blood pressure readings for a group of clients on a medical unit. Which client is at the highest risk for complications related to hypertension?
- A. Post-menopausal Caucasian female who overeats and is 20% above her ideal body weight.
- B. Young adult Hispanic female who has hemoglobin at 11 g/dl (110 g/L) and drinks beer daily.
- C. Older adult who consumes a diet of smoked, cured, and pickled foods.
- D. Middle-aged African-American male who has a serum creatinine level of 2.9 mg/dL (256.4 micromol/L).
Correct Answer: D
Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.
An overweight, young adult male who was recently diagnosed with type 2 diabetes mellitus is admitted for a hernia repair. He tells the nurse that he is feeling very weak and jittery. Which actions should the nurse implement? (Select all that apply)
- A. Check his fingerstick glucose
- B. Assess his skin temperature and moisture
- C. Measure his pulse and BP
- D. All of the Above
Correct Answer: D
Rationale: In this scenario, the patient is a young adult male with type 2 diabetes mellitus admitted for a hernia repair who is experiencing weakness and jitteriness. Checking his fingerstick glucose is crucial to assess his blood sugar levels, which can directly impact his symptoms. Assessing his skin temperature and moisture is important to evaluate his peripheral circulation and hydration status. Measuring his pulse and blood pressure helps in gauging his cardiovascular status. Therefore, all the actions mentioned in choices A, B, and C are appropriate for the nurse to implement in this situation to identify the underlying cause of the patient's symptoms. Choice D, 'All of the Above,' is the correct answer because all these actions are necessary for a comprehensive assessment of the patient's condition. Choices A, B, and C are incorrect individually as they each address different aspects of the patient's condition, and a holistic approach is needed to provide optimal care in this situation.
A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?
- A. Hypoglycemia
- B. Diabetic ketoacidosis (DKA)
- C. Hyperosmolar hyperglycemic state (HHS)
- D. Insulin shock
Correct Answer: B
Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.
