Nursing Elites

1. 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.

2. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?

• A. Encourage the client to eat foods rich in potassium
• B. Administer a potassium-sparing diuretic
• C. Administer a potassium-binding medication
• D. Hold all medications containing potassium

Correct answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.

3. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

4. 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.

5. The nurse is preparing to administer an intramuscular injection to an adult client. Which site should the nurse select?

• A. Deltoid muscle
• B. Ventrogluteal muscle
• C. Vastus lateralis muscle
• D. Dorsogluteal muscle

Correct answer: B

Rationale: The ventrogluteal site is preferred for intramuscular injections in adults because it is free from major blood vessels and nerves, reducing the risk of injury. The deltoid muscle can be used for smaller volumes of medication, primarily vaccines. The vastus lateralis muscle is commonly used in infants, toddlers, and young children. The dorsogluteal muscle site is discouraged due to its proximity to the sciatic nerve, increasing the risk of injury or nerve damage.
