Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

• A. Prothrombin time (PT)
• B. Hemoglobin and hematocrit (H&H)
• C. International Normalized Ratio (INR)
• D. Partial thromboplastin time (PTT)

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.

2. A client with a venous leg ulcer is receiving compression therapy. What assessment finding requires immediate intervention?

• A. Decreased pain and increased redness around the ulcer.
• B. Increased serous drainage from the ulcer site.
• C. Cool extremities and weak peripheral pulses.
• D. Pitting edema around the ulcer site.

Correct answer: C

Rationale: The correct answer is C. Cool extremities and weak peripheral pulses indicate compromised circulation, possibly due to inadequate arterial blood supply. This finding requires immediate intervention to prevent further complications such as tissue damage or non-healing ulcers. Option A, decreased pain and increased redness, can be a sign of improving wound condition. Option B, increased serous drainage, may indicate a normal part of the healing process. Option D, pitting edema, is common in venous leg ulcers and may not require immediate intervention unless severe and accompanied by other concerning symptoms.

3. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

4. When teaching a group of mothers of young children about emergency care for poisoning, which of the following statements should be included?

• A. Induce vomiting immediately after the poison ingestion
• B. Call the local Poison Control Center after inducing vomiting
• C. Call the Poison Control Center prior to any interventions
• D. Take the child to the emergency department before calling the Poison Control Center

Correct answer: C

Rationale: The correct statement to include when teaching about emergency care for poisoning is to call the Poison Control Center prior to any interventions. This is important because the Poison Control Center can provide guidance on the appropriate steps to take based on the type of poisoning, the amount ingested, and the age of the child. Inducing vomiting without professional advice can sometimes do more harm than good. Choice A is incorrect because inducing vomiting immediately is not recommended without consulting with professionals. Choice B is incorrect as it suggests calling the Poison Control Center after inducing vomiting, which is not the recommended sequence. Choice D is incorrect because it is advisable to contact the Poison Control Center first before taking the child to the emergency department.

5. A client receiving heparin therapy develops sudden chest pain and dyspnea. What should the nurse do first?

• A. Administer oxygen and elevate the head of the bed.
• B. Administer sublingual nitroglycerin as prescribed.
• C. Assess for signs of bleeding at the injection site.
• D. Administer a PRN dose of albuterol.

Correct answer: A

Rationale: In this scenario, the priority action for the nurse is to administer oxygen and elevate the head of the bed. These interventions help relieve dyspnea and chest pain, which can be indicative of a pulmonary embolism or other complications during heparin therapy. Administering nitroglycerin (Choice B) is not the initial priority in this situation as the client's symptoms are not suggestive of angina. Assessing for bleeding (Choice C) is important but not the first action needed to address chest pain and dyspnea. Administering albuterol (Choice D) is not indicated unless there are specific respiratory issues requiring it, which are not described in the scenario.
