Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

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

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.

3. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What should the nurse do next?

• A. Apply a pressure dressing at the chest tube site.
• B. Administer an oral antihistamine per PRN order.
• C. Assess the client for allergies to topical cleaning agents.
• D. Measure the area of crackling and swelling.

Correct answer: D

Rationale: Measuring the area of crackling and swelling is essential in monitoring the progression of subcutaneous emphysema, which can result from air leaking into the tissues around the chest tube insertion site. This technique helps evaluate the extent of the issue and guides further interventions. Applying a pressure dressing (choice A) might exacerbate the condition by trapping more air. Administering an oral antihistamine (choice B) is not indicated for subcutaneous emphysema. Assessing for allergies to topical cleaning agents (choice C) is not the priority in this situation compared to evaluating and managing the subcutaneous emphysema.

4. A male client with heart failure presents with shortness of breath, audible wheezing, and pink frothy sputum. What action should the nurse take?

• A. Consult with the charge nurse regarding morphine prescription.
• B. Administer the dose of morphine sulfate as prescribed.
• C. Withhold morphine until dyspnea resolves.
• D. Review the need for the prescription with the healthcare provider.

Correct answer: B

Rationale: The correct answer is B: Administer the dose of morphine sulfate as prescribed. In heart failure, morphine helps reduce anxiety, preload, and afterload on the heart, improving oxygenation. The client's symptoms indicate acute decompensated heart failure, and morphine should be administered promptly to relieve distress. Consulting the charge nurse (Choice A) or withholding morphine (Choice C) would delay necessary treatment. Reviewing the prescription with the healthcare provider (Choice D) is not needed in this acute situation.

5. An adult male is brought to the ER after a motorcycle accident with periorbital bruising and bloody drainage from both ears. Which finding requires immediate attention?

• A. Rebound abdominal tenderness.
• B. Diminished breath sounds bilaterally.
• C. Rib pain with deep inspiration.
• D. Projectile vomiting.

Correct answer: D

Rationale: In this scenario, the patient's periorbital bruising and bloody drainage from both ears suggest a severe head injury. Projectile vomiting is a red flag symptom that may indicate increased intracranial pressure, which requires immediate attention to prevent further neurological deterioration. Rebound abdominal tenderness (choice A) typically indicates peritonitis and is not directly related to the primary head injury. Diminished breath sounds bilaterally (choice B) suggest a pneumothorax or hemothorax, which are important but not as immediately life-threatening in this context. Rib pain with deep inspiration (choice C) is concerning for rib fractures or pulmonary contusion, which are also important but do not take precedence over addressing the potential increased intracranial pressure.
