1. Which of the following is a common cause of chronic obstructive pulmonary disease (COPD)?

• A. Smoking
• B. Asthma
• C. Allergies
• D. Chronic bronchitis

Correct answer: A

Rationale: Smoking is the correct answer as it is a well-established common cause of chronic obstructive pulmonary disease (COPD). Smoking leads to long-term damage to the lungs, contributing to the development of COPD. Choice B, asthma, is not a cause but a separate respiratory condition characterized by airway inflammation and hyperresponsiveness. Allergies, choice C, are not a direct cause of COPD but can exacerbate symptoms in individuals with existing COPD. Chronic bronchitis, choice D, is a type of COPD, not a cause of COPD itself, making it an incorrect choice in this context.

2. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

3. During an assessment on a patient brought to the emergency department for treatment for dehydration, the nurse notes a respiratory rate of 26 breaths/minute, a heart rate of 110 beats/minute, a blood pressure of 86/50 mm Hg, and a temperature of 39.5° C. The patient becomes dizzy when transferred from the wheelchair to a bed. The nurse observes cool, clammy skin. Which diagnosis does the nurse suspect?

• A. Fluid volume deficit (FVD)
• B. Fluid volume excess (FVE)
• C. Mild extracellular fluid (ECF) deficit
• D. Renal failure

Correct answer: A

Rationale: The nurse should suspect Fluid Volume Deficit (FVD) in this patient. Signs of FVD include elevated temperature, tachycardia, tachypnea, hypotension, orthostatic hypotension, and cool, clammy skin, which align with the patient's assessment findings. Choices B, C, and D are incorrect. Fluid Volume Excess (FVE) typically presents with bounding pulses, elevated blood pressure, dyspnea, and crackles. Mild extracellular fluid (ECF) deficit usually manifests as thirst. Renal failure commonly results in Fluid Volume Excess (FVE) rather than Fluid Volume Deficit (FVD).

4. After an endotracheal tube is placed in a client who experienced sudden onset of respiratory distress, what should the nurse do?

• A. Secure the tube in place with tape
• B. Order a chest x-ray for the client
• C. Document the depth of tube insertion
• D. Auscultate both lungs for breath sounds

Correct answer: D

Rationale: After endotracheal tube insertion, the nurse should auscultate both lungs for the presence of breath sounds. This step helps confirm proper tube placement and adequate ventilation. Auscultation of breath sounds is crucial to ensure that the tube is correctly positioned in the trachea and not in the esophagus. While securing the tube with tape is important, it is not the immediate priority after insertion. Ordering a chest x-ray may be necessary but is not the first action to take immediately post-intubation. Documenting the depth of tube insertion is important but ensuring proper ventilation through auscultation takes precedence.

5. The patient is receiving a high dose of intravenous azithromycin to treat an infection and taking acetaminophen for pain. The nurse should expect to review which lab values when monitoring for this drug’s side effects?

• A. Complete blood counts
• B. Electrolytes
• C. Liver enzymes
• D. Urinalysis

Correct answer: C

Rationale: When a patient is receiving a high dose of intravenous azithromycin, which is a macrolide antibiotic, in combination with acetaminophen, a potentially hepatotoxic drug, the nurse should monitor liver enzymes. High doses of macrolides when taken with hepatotoxic drugs like acetaminophen can lead to hepatotoxicity. Reviewing liver enzymes helps in early detection of liver damage. Complete blood counts (Choice A) are not typically affected by azithromycin or acetaminophen. Electrolytes (Choice B) are not directly impacted by these medications. Urinalysis (Choice D) is not specifically indicated for monitoring the side effects of azithromycin and acetaminophen combination therapy.
