1. Polyethylene glycol–electrolyte solution (GoLYTELY) is prescribed for a hospitalized client scheduled for a colonoscopy. The client begins to experience diarrhea after drinking the solution. Which action by the nurse is appropriate?
- A. Calling the physician
- B. Administering a cleansing enema
- C. Documenting the diarrhea in the medical record
- D. Giving intravenous replacement fluids in large amounts
Correct answer: C
Rationale: The correct action by the nurse in this situation is to document the diarrhea in the medical record. Polyethylene glycol–electrolyte solution (GoLYTELY) is a bowel evacuant used to cleanse the bowel before a colonoscopy. It is expected to cause mild diarrhea, which is a normal response to the medication. The diarrhea helps clear the bowel in preparation for the procedure. Calling the physician is not necessary unless there are complications. Administering a cleansing enema or giving intravenous replacement fluids in large amounts are not appropriate actions as they are not indicated for managing the expected diarrhea caused by GoLYTELY.
2. A young adult client, admitted to the Emergency Department following a motor vehicle collision, is transfused with 4 units of PRBCs (packed red blood cells). The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all the PRBCs have been transfused?
- A. 0.19
- B. 0.09
- C. 0.39
- D. 0.29
Correct answer: D
Rationale: The expected increase in hematocrit after transfusion is approximately 3% per unit of PRBCs. Since the client received 4 units, the expected increase would be 4 x 3% = 12%. Therefore, adding this to the pretransfusion hematocrit of 17% would result in an expected post-transfusion hematocrit of 29%. Choice A (0.19) is incorrect as it doesn't consider the incremental increase per unit of PRBCs. Choices B (0.09) and C (0.39) are also incorrect as they do not align with the expected increase in hematocrit following the transfusion of 4 units of PRBCs.
3. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:
- A. 1 L/min
- B. 3 L/min
- C. 4 L/min
- D. 6 L/min
Correct answer: B
Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.
4. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?
- A. Administering insulin
- B. Administering IV fluids
- C. Administering oral glucose
- D. Administering oral fluids
Correct answer: A
Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.
5. A male client expresses concern about how a hypophysectomy will affect his sexual function. Which of the following statements provides the most accurate information about the physiologic effects of hypophysectomy?
- A. Removing the source of excess hormone should restore the client's libido, erectile function, and fertility.
- B. Potency will be restored, but the client will remain infertile.
- C. Fertility will be restored, but impotence and decreased libido will persist.
- D. Exogenous hormones will be needed to restore erectile function after the adenoma is removed.
Correct answer: A
Rationale: Choice A is the most accurate statement regarding the physiologic effects of hypophysectomy on sexual function. The client's sexual problems are directly related to excessive hormone levels. Removing the source of excess hormone secretion through hypophysectomy should allow the client to return to a normal physiologic pattern, which includes restoring libido, erectile function, and fertility. Choices B, C, and D are incorrect. Choice B incorrectly states that the client will remain infertile, which is not necessarily true after a hypophysectomy. Choice C inaccurately suggests that fertility will be restored while impotence and decreased libido will persist, which is not aligned with the expected outcomes of hypophysectomy. Choice D is incorrect because exogenous hormones are typically not needed to restore erectile function after the adenoma is removed; rather, the removal of the source of excessive hormone secretion should address the sexual function concerns.
