1. A nurse is teaching a newly licensed nurse about the stages of wound healing. The nurse should include in the teaching that collagen is added to the wound during which of the following stages?
- A. Hemostasis phase.
- B. Inflammatory phase.
- C. Proliferative phase.
- D. Maturation phase.
Correct answer: C
Rationale: The correct answer is C: Proliferative phase. During the proliferative phase of wound healing, collagen is added to the wound to promote tissue regeneration. In the hemostasis phase (choice A), the primary goal is to stop bleeding by forming a blood clot. The inflammatory phase (choice B) involves cleaning the wound and preparing it for healing. The maturation phase (choice D) is when the wound undergoes remodeling and gains strength, but collagen addition primarily occurs during the proliferative phase.
2. 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.
3. Which medication is used to reverse the effects of opioid overdose?
- A. Naloxone
- B. Epinephrine
- C. Atropine
- D. Lidocaine
Correct answer: A
Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.
4. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?
- A. PaO2 of 95 mm Hg
- B. PaCO2 of 55 mm Hg
- C. HCO3 of 24 mEq/L
- D. pH level of 7.35
Correct answer: B
Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.
5. A nurse is reviewing the laboratory values of a client who has liver cirrhosis. Which of the following findings should the nurse report to the provider?
- A. Bilirubin 0.8 mg/dL
- B. Ammonia 35 mcg/dL
- C. Prothrombin time 16 seconds
- D. Albumin 4 g/dL
Correct answer: C
Rationale: In clients with liver cirrhosis, an elevated prothrombin time indicates impaired liver function and decreased production of clotting factors. This finding should be reported to the provider for further evaluation and management. Choices A, B, and D are within normal ranges and do not specifically indicate worsening liver cirrhosis. Bilirubin 0.8 mg/dL is normal, ammonia 35 mcg/dL is within the reference range, and albumin 4 g/dL is also within the normal range for this client population.
