Endocrinology Exam
1. A nurse is to administer a unit of whole blood to a postoperative client. What does the nurse do to ensure the safety of the blood transfusion?
- A. Asks the client to both say and spell their full name before starting the blood transfusion
- B. Ensures that another qualified healthcare professional checks the unit before administering
- C. Checks the blood identification numbers with the laboratory technician at the Blood Bank at the time it is dispersed
- D. Ensures that all staff wear appropriate personal protective equipment during the transfusion process
Correct answer: Checks the blood identification numbers with the laboratory technician at the Blood Bank at the time it is dispersed
Rationale: Ensuring the safety of a blood transfusion is crucial to prevent potential errors or adverse reactions. Checking the blood identification numbers with the laboratory technician at the Blood Bank when the blood is dispersed helps confirm that the correct blood product is being administered to the right patient, reducing the risk of transfusion reactions. The other choices are incorrect because asking the client to say and spell their full name (Choice A) is a part of the identification process but not specific to ensuring the safety of the blood transfusion. While having another qualified healthcare professional check the unit (Choice B) is a good practice, the direct verification with the Blood Bank technician is a more critical step in ensuring the correct blood product is administered. Choice D is irrelevant to ensuring the safety of the blood transfusion as it addresses infection control measures.
2. What is the primary intervention for a client diagnosed with delirium?
- A. Provide a quiet and calm environment to minimize confusion
- B. Administer medication to reverse the symptoms of delirium
- C. Provide opportunities for social interaction to reduce isolation
- D. Encourage the client to remain physically active
Correct answer: A
Rationale: The correct answer is A: Provide a quiet and calm environment to minimize confusion. For clients diagnosed with delirium, creating a tranquil setting can help reduce agitation and disorientation. This intervention aims to decrease stimuli that may exacerbate symptoms. Administering medication (choice B) is not the primary intervention for delirium; it is usually reserved for specific underlying causes. While social interaction (choice C) and physical activity (choice D) are beneficial for overall well-being, they are not the primary interventions for managing delirium.
3. The nurse is administering enoxaparin (Lovenox) to a client. What is the most important lab value to monitor?
- A. Platelet count
- B. Hemoglobin
- C. White blood cell count
- D. aPTT
Correct answer: A
Rationale: The correct answer is A: Platelet count. When administering enoxaparin, it is crucial to monitor the platelet count because enoxaparin can lead to a rare but serious side effect known as thrombocytopenia, which is a decrease in platelet levels. Monitoring the platelet count helps in detecting this adverse effect early. Choices B, C, and D are incorrect because hemoglobin, white blood cell count, and aPTT are not the most important lab values to monitor specifically for enoxaparin administration.
4. This is a branch of the left coronary arteries which supplies the LEFT ATRIUM, posterior lateral surface of the left ventricle.
- A. Right coronary artery
- B. Left circumflex artery
- C. Left anterior descending artery
- D. Posterior descending artery
Correct answer: B
Rationale: The correct answer is B, Left circumflex artery. The circumflex artery is a branch of the left coronary artery that supplies blood to the left atrium and the lateral wall of the left ventricle. Choice A, the Right coronary artery, does not supply the mentioned areas. Choice C, the Left anterior descending artery, supplies the anterior wall of the left ventricle. Choice D, the Posterior descending artery, is a branch of the right coronary artery and supplies the inferior wall of the left ventricle and the posterior septum.
5. Which pathophysiologic process causes the decreased glomerular filtration rate in a patient with acute glomerulonephritis?
- A. Decreased renal-induced constriction of the renal arteries
- B. Immune complex deposition, increased capillary permeability, and cellular proliferation
- C. Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
- D. Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis
Correct answer: B
Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. In acute glomerulonephritis, immune complexes deposit in the glomerulus, leading to inflammation, increased capillary permeability, and cellular proliferation. These processes collectively reduce the glomerular filtration rate. Choices A, C, and D do not accurately describe the pathophysiologic process in acute glomerulonephritis. Decreased renal-induced constriction of the renal arteries, necrosis of nephrons due to increased kidney interstitial hydrostatic pressure, and scar tissue formation in the proximal convoluted tubule are not the primary mechanisms responsible for the decreased filtration rate in this condition.
