Nursing Elites

1. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.

2. For a patient with asthma, what is the primary purpose of prescribing salmeterol?

• A. Relieve acute bronchospasm
• B. Prevent asthma attacks
• C. Suppress cough
• D. Thin respiratory secretions

Correct answer: B

Rationale: Salmeterol is classified as a long-acting beta2-agonist, which is used to prevent asthma attacks by providing extended bronchodilation. It is not typically used for immediate relief of acute bronchospasm or for suppressing cough. Additionally, salmeterol does not have the primary purpose of thinning respiratory secretions.

3. A client returns to the unit after a neck dissection. The surgeon placed a Jackson-Pratt drain in the wound. When assessing the wound drainage over the first 24 postoperative hours, what finding would prompt the nurse to notify the health care provider immediately?

• A. Presence of small blood clots in the drainage
• B. 60 mL of milky or cloudy drainage
• C. Spots of drainage on the dressings surrounding the drain
• D. 120 mL of serosanguinous drainage

Correct answer: B

Rationale: Milky or cloudy drainage can indicate infection or lymphatic leakage, which requires immediate attention. This finding may suggest a serious complication post neck dissection, warranting prompt notification of the healthcare provider for further evaluation and intervention.

4. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

5. A client with portal hypertension who has developed ascites is scheduled for a paracentesis. What pre-procedure nursing intervention is essential?

• A. Encourage the client to empty the bladder
• B. Administer a laxative to clear the bowels
• C. Restrict the client's fluid intake
• D. Place the client in a supine position

Correct answer: A

Rationale: Emptying the bladder before a paracentesis is essential to prevent bladder injury during the procedure. A full bladder may be in the path of the needle insertion, increasing the risk of bladder puncture. Encouraging the client to empty the bladder ensures their safety and reduces the likelihood of complications.
