What is the best intervention for a patient experiencing hypoxia?
- A. Administer oxygen
- B. Reposition the patient
- C. Provide humidified air
- D. Provide chest physiotherapy
Correct Answer: A
Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

A nurse is providing teaching to a client who has a new diagnosis of hypertension. Which of the following dietary recommendations should the nurse include?
- A. Limit sodium intake to 4 grams per day.
- B. Limit protein intake to 80 grams per day.
- C. Limit saturated fat intake to 7% of daily calories.
- D. Limit fluid intake to 1,500 mL per day.
Correct Answer: C
Rationale: The correct answer is to limit saturated fat intake to 7% of daily calories. This recommendation is crucial for clients with hypertension to lower cholesterol levels and promote heart health. Choice A, limiting sodium intake to 4 grams per day, is important for hypertension but not the best recommendation compared to limiting saturated fats. Choice B, limiting protein intake to 80 grams per day, is not a primary dietary concern for hypertension. Choice D, limiting fluid intake to 1,500 mL per day, is not a standard recommendation for hypertension management.
A nurse is assessing a client who has a new diagnosis of heart failure. Which of the following findings should the nurse report to the provider?
- A. Heart rate of 90/min
- B. Serum potassium level of 4.0 mEq/L
- C. Weight gain of 2 kg (4.4 lb) in 2 days
- D. Heart rate of 76/min
Correct Answer: C
Rationale: A weight gain of 2 kg (4.4 lb) in 2 days can indicate fluid retention, which is a sign of worsening heart failure and should be reported. This rapid weight gain suggests a fluid overload, putting the client at risk for complications. A heart rate of 90/min is slightly elevated but not as concerning as a sudden significant weight gain. The serum potassium level of 4.0 mEq/L is within the normal range and does not directly indicate worsening heart failure. A heart rate of 76/min is within the normal range and does not raise immediate concerns related to heart failure.
What is the best way to assess a patient's respiratory function after surgery?
- A. Check oxygen saturation
- B. Auscultate lung sounds
- C. Check for abnormal breath sounds
- D. Check skin color
Correct Answer: A
Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.
A client is receiving discharge teaching for a new prescription of warfarin. Which statement by the client indicates an understanding of the teaching?
- A. I will need to increase my intake of leafy green vegetables.
- B. I will avoid drinking grapefruit juice while taking warfarin.
- C. I will have my INR checked regularly.
- D. I will take my medication at the same time each day.
Correct Answer: C
Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.
Which lab value is critical for a patient on heparin therapy?
- A. Monitor aPTT
- B. Monitor INR
- C. Monitor platelet count
- D. Monitor sodium levels
Correct Answer: A
Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.
