1. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?
- A. Elevate the head of the bed to 30 degrees.
- B. Administer diuretics to reduce fluid volume.
- C. Administer corticosteroids to reduce inflammation.
- D. Keep the patient in a supine position.
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.
2. A client has driven himself to the emergency department. He is 50 years old, has a history of hypertension, and informs the nurse that his father died from a heart attack at age 60. The client has indigestion. The nurse connects him to an electrocardiogram monitor and begins administering oxygen at 2 L/min via nasal cannula. What should the nurse do next?
- A. Call for the physician.
- B. Start an IV infusion.
- C. Obtain a portable chest radiograph.
- D. Draw blood for laboratory studies.
Correct answer: B
Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.
3. The nurse is preparing to administer trimethoprim-sulfamethoxazole (TMP-SMX) to a patient who is being treated for a urinary tract infection. The nurse learns that the patient has type 2 diabetes mellitus and takes a sulfonylurea oral antidiabetic drug. The nurse will monitor this patient closely for which effect?
- A. Headaches
- B. Hypertension
- C. Hypoglycemia
- D. Superinfection
Correct answer: C
Rationale: When a patient takes oral antidiabetic agents (sulfonylurea) along with sulfonamides like trimethoprim-sulfamethoxazole, it can lead to an increased hypoglycemic effect. Therefore, the nurse should monitor the patient closely for hypoglycemia. Headaches, hypertension, and superinfection are not typically associated with the interaction between sulfonamides and sulfonylureas. Examples of antidiabetic sulfonylurea medications include glipizide, glimepiride, glyburide, tolazamide, and tolbutamide.
4. The nurse is assessing a client with chronic kidney disease (CKD). Which finding is most important for the nurse to respond to first?
- A. Potassium 6.0 mEq/L.
- B. Daily urine output of 400 ml.
- C. Peripheral neuropathy.
- D. Uremic fetor.
Correct answer: A
Rationale: The correct answer is A. Potassium level of 6.0 mEq/L indicates hyperkalemia, which is a critical electrolyte imbalance in clients with chronic kidney disease. Hyperkalemia can lead to life-threatening arrhythmias, making it the priority finding to address. Choice B, a daily urine output of 400 ml, may indicate decreased kidney function but does not pose an immediate life-threatening risk compared to hyperkalemia. Peripheral neuropathy (Choice C) and uremic fetor (Choice D) are common manifestations of CKD but are not as urgent as addressing a potentially fatal electrolyte imbalance like hyperkalemia.
5. A client with elevated levels of antidiuretic hormone (ADH) triggers the release of this hormone due to which disorder?
- A. Pneumonia
- B. Dehydration
- C. Renal failure
- D. Edema
Correct answer: B
Rationale: Antidiuretic hormone (ADH) increases tubular permeability to water, causing more water absorption into the capillaries. ADH is released in response to a rising extracellular fluid osmolarity, such as in dehydration. Pneumonia, renal failure, and edema do not typically lead to the release of ADH. Pneumonia is an inflammatory lung condition, renal failure affects kidney function, and edema is the accumulation of excess fluid in the tissues, none of which directly stimulate the release of ADH.
