Nokea
A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?
- A. Anesthesia reaction
- B. Hyperglycemia
- C. Hypoglycemia
- D. Diabetic ketoacidosis
Correct Answer: C
Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.

After assessing Mr. B, what is the initial action of the nurse?
- A. Immediately place the client in a negative-pressure room
- B. Set the client up to receive a bronchoscopy
- C. Contact the physician for antifungal medications
- D. Administer oxygen and assist the client to sit in the semi-Fowler's position
Correct Answer: A
Rationale: The first action the nurse should take after assessing Mr. B is to administer oxygen and assist him to sit in the semi-Fowler's position. Administering oxygen helps improve tissue oxygenation, while sitting up in a semi-Fowler's position aids in better breathing and secretion clearance. Placing the client in a negative-pressure room is not the immediate priority unless isolation is needed. Performing a bronchoscopy or contacting the physician for antifungal medications is not the initial step in managing a client with suspected pneumonia.
Rhogam is most often used to treat____ mothers that have a ____ infant.
- A. RH positive, RH positive
- B. RH positive, RH negative
- C. RH negative, RH positive
- D. RH negative, RH negative
Correct Answer: C
Rationale: Rhogam is administered to RH-negative mothers who have an RH-positive infant to prevent the development of anti-RH antibodies in the mother's system. Choice A (RH positive, RH positive) is incorrect because Rhogam is not used when both mother and infant are RH positive. Choice B (RH positive, RH negative) is incorrect because Rhogam is used when the mother is RH negative, not RH positive. Choice D (RH negative, RH negative) is incorrect as Rhogam is not typically needed if both mother and infant are RH negative.
A patient is admitted to the same-day surgery unit for a liver biopsy. Which of the following laboratory tests assesses coagulation? Select one that doesn't apply.
- A. Partial thromboplastin time
- B. Prothrombin time
- C. Platelet count
- D. Hemoglobin
Correct Answer: D
Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.
A fragile 87-year-old female has recently been admitted to the hospital with increased confusion and falls over the last two weeks. She is also noted to have a mild left hemiparesis. Which of the following tests is most likely to be performed?
- A. CBC (Complete Blood Count)
- B. ECG (Electrocardiogram)
- C. Thyroid Function Tests
- D. CT Scan
Correct Answer: D
Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.
A client with myocardial infarction is receiving tissue plasminogen activator, alteplase (Activase, tPA). While on the therapy, the nurse plans to prioritize which of the following?
- A. Observe for neurological changes
- B. Monitor for any signs of renal failure
- C. Check the food diary
- D. Observe for signs of bleeding
Correct Answer: D
Rationale: The priority concern for a client receiving thrombolytic medication, such as tissue plasminogen activator (alteplase), is to monitor for signs of bleeding. Thrombolytics work by converting plasminogen to plasmin, which degrades fibrin. This process can lead to the breakdown of both fibrin-bound plasminogen on thrombi surfaces and unbound plasminogen in the plasma. The resulting plasmin can degrade fibrin, fibrinogen, factor V, and factor VIII. Observing for signs of bleeding is crucial due to the increased risk of hemorrhage associated with thrombolytic therapy. Monitoring for neurological changes, signs of renal failure, or checking the food diary are not the immediate priorities compared to detecting and managing potential bleeding complications.
