Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

2. The hypertonicity of the muscles in an infant with cerebral palsy causes scissoring of the legs. The nurse teaches the mother that the preferred way to carry the infant is in a sitting position:

• A. Astride one of her hips
• B. Strapped in an infant seat
• C. Wrapped tightly in a blanket
• D. Under the arm using a football hold

Correct answer: A

Rationale: The correct way to carry an infant with cerebral palsy experiencing muscle hypertonicity and scissoring of the legs is astride one of the mother's hips. This position helps keep the infant's legs apart, reducing muscle tightness. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm does not address the specific needs related to muscle hypertonicity and scissoring of the legs in cerebral palsy.

3. Which question should the healthcare provider ask when assessing the client for an endocrine dysfunction?

• A. “Have you noticed any pain in your legs when walking?”
• B. “Have you had any unexplained weight loss?”
• C. “Have you noticed any change in your bowel movements?”
• D. “Have you experienced any joint pain or discomfort?”

Correct answer: B

Rationale: The correct answer is B: “Have you had any unexplained weight loss?” Unexplained weight loss can be a significant symptom of various endocrine disorders, such as hyperthyroidism and diabetes. Weight changes are often closely linked to endocrine dysfunction due to the hormonal imbalances affecting metabolism. Choices A, C, and D are less specific to endocrine dysfunction. Pain in the legs, changes in bowel movements, and joint pain or discomfort are symptoms that can be related to various health conditions but are not as indicative of endocrine disorders as unexplained weight loss.

4. The nurse is caring for clients on a cardiac floor. Which client should the nurse assess first?

• A. The client with three (3) unifocal PVCs in a minute
• B. The client diagnosed with coronary artery disease who wants to ambulate
• C. The client diagnosed with mitral valve prolapse with an audible S3
• D. The client diagnosed with pericarditis who is in normal sinus rhythm

Correct answer: C

Rationale: The correct answer is C because an audible S3 in a client with mitral valve prolapse could indicate heart failure and requires immediate assessment. Choice A is not as urgent as an audible S3 in mitral valve prolapse. Choice B, a client with coronary artery disease wanting to ambulate, does not present an immediate concern compared to a potential heart failure indicated by an audible S3. Choice D, a client with pericarditis in normal sinus rhythm, is stable and does not require immediate attention when compared to a potential heart failure situation signified by an audible S3 in mitral valve prolapse.

5. The client diagnosed with acute pancreatitis has developed a pseudocyst that ruptures. Which procedure should the nurse anticipate the HCP ordering?

• A. Paracentesis
• B. Chest tube insertion
• C. Lumbar puncture
• D. Biopsy of the pancreas

Correct answer: B

Rationale: The correct answer is B: Chest tube insertion. In the context of a pancreatic pseudocyst rupturing, a chest tube may be needed if the pseudocyst extends into the pleural space, leading to a pleural effusion. Choice A, paracentesis, involves the removal of fluid from the abdominal cavity, not the pleural space. Choice C, lumbar puncture, is a procedure performed to collect cerebrospinal fluid from the spinal canal, not relevant in this scenario. Choice D, biopsy of the pancreas, is not indicated in the immediate management of a ruptured pseudocyst.
