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. A patient who is diagnosed with cervical cancer that is classified as Tis, N0, M0 asks the nurse what the letters and numbers mean. Which response by the nurse is most appropriate?

• A. The cancer involves only the cervix.
• B. The cancer cells closely resemble normal cells.
• C. Further testing is necessary to determine the spread of the cancer.
• D. Determining the original site of the cervical cancer is challenging.

Correct answer: A

Rationale: The correct response is A: 'The cancer involves only the cervix.' In staging, 'Tis' indicates cancer in situ, which means it is localized to the cervix and not invasive at this time. The differentiation of cancer cells is not part of clinical staging. Since the cancer is in situ, its origin is the cervix. Further testing is not required as the cancer has not spread beyond the cervix. Choice B is incorrect as the staging information provided does not relate to the resemblance of cancer cells to normal cells. Choice C is incorrect because further testing is not necessary as the cancer is localized. Choice D is incorrect because the staging information provided clearly indicates the site of origin as the cervix.

3. The client has received 250 ml of 0.9% normal saline through the IV line in the last hour. The client is now tachypneic and has a pulse rate of 120 beats/minute, with a pulse volume of +4. In addition to reporting the assessment findings to the healthcare provider, what action should the nurse implement?

• A. Discontinue the IV and apply pressure at the site.
• B. Decrease the saline to a keep-open rate.
• C. Increase the rate of the current IV solution.
• D. Change the IV fluid to 0.45% normal saline at the same rate.

Correct answer: B

Rationale: In this scenario, the client is showing signs of fluid overload with tachypnea and a high pulse rate. Decreasing the saline to a keep-open rate is appropriate to prevent further fluid volume excess. This action allows for IV access to be maintained while reducing the fluid administered, helping to manage the symptoms of fluid overload.

4. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.

5. A patient with an anxiety disorder is prescribed alprazolam. What is the primary action of this medication?

• A. Increase energy levels
• B. Induce sedation
• C. Elevate mood
• D. Reduce anxiety

Correct answer: D

Rationale: Alprazolam is a benzodiazepine that primarily works by reducing anxiety. It achieves this by enhancing the inhibitory effects of the neurotransmitter GABA in the brain, which leads to a calming effect on the individual. Therefore, the primary action of alprazolam is to decrease anxiety levels rather than increase energy, induce sedation, or elevate mood.
