1. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?
- A. PaO2 level of 89 mm Hg
- B. PaCO2 level of 55 mm Hg
- C. HCO3 level of 25 mEq/L
- D. pH level of 7.37
Correct answer: B
Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.
2. How should a healthcare professional assess a patient for dehydration?
- A. Check for skin turgor
- B. Monitor blood pressure
- C. Check for dry mucous membranes
- D. Monitor urine output
Correct answer: A
Rationale: Checking for skin turgor is a reliable method to assess dehydration in patients. Skin turgor refers to the skin's elasticity and hydration status. When a healthcare professional gently pinches the skin on the back of the patient's hand or forearm, dehydration is indicated by the skin not snapping back immediately. Monitoring blood pressure (choice B) is important but is more indicative of cardiovascular status rather than dehydration specifically. Checking for dry mucous membranes (choice C) can be a sign of dehydration, but skin turgor is a more direct assessment. Monitoring urine output (choice D) is also essential but may not provide immediate feedback on hydration status as skin turgor does.
3. A nurse is planning care for a client who has dementia and is frequently agitated. Which of the following interventions should the nurse include in the plan of care?
- A. Offer the client several choices when scheduling activities.
- B. Confront the client when inappropriate behavior occurs.
- C. Use a calm, reassuring approach when speaking to the client.
- D. Encourage the client to engage in stimulating activities.
Correct answer: C
Rationale: The correct intervention for a client with dementia who is frequently agitated is to use a calm and reassuring approach when speaking to them. This approach helps reduce agitation and create a more therapeutic environment. Offering several choices may overwhelm the client and increase agitation, making choice A incorrect. Confronting the client can escalate the situation and worsen agitation, making choice B inappropriate. While encouraging stimulating activities is beneficial, it may not be the most effective intervention for immediate agitation management, making choice D less priority compared to using a calm and reassuring approach.
4. Which lab value should be closely monitored for a patient receiving heparin therapy?
- A. Monitor aPTT
- B. Monitor INR
- C. Monitor potassium levels
- D. Monitor sodium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.
5. A patient is being cared for by a nurse who has a history of angina and is experiencing chest pain. Which of the following actions should the nurse take first?
- A. Administer oxygen at 2 L/min via nasal cannula.
- B. Administer nitroglycerin sublingually.
- C. Obtain a 12-lead ECG.
- D. Notify the healthcare provider.
Correct answer: C
Rationale: In a patient with a history of angina experiencing chest pain, the priority action for the nurse is to obtain a 12-lead ECG. This helps in assessing for myocardial infarction, a serious condition that requires immediate attention. Administering oxygen, nitroglycerin, or notifying the healthcare provider can be important interventions but obtaining the ECG comes first to determine the presence of myocardial infarction and guide further management.
