LPN Pharmacology Practice Questions
1. A client with a history of angina pectoris reports chest pain while ambulating in the corridor. What should the nurse do first?
- A. Check the client's vital signs.
- B. Assist the client to sit or lie down.
- C. Administer sublingual nitroglycerin.
- D. Apply nasal oxygen at a rate of 2 L/min.
Correct answer: B
Rationale: When a client with a history of angina pectoris experiences chest pain while ambulating, the priority action for the nurse is to assist the client to sit or lie down. This helps reduce the demand on the heart by decreasing physical exertion. Checking vital signs, administering medication, or applying oxygen can follow once the client is in a more comfortable position. Checking vital signs (Choice A) may be important but addressing the immediate discomfort by positioning the client comfortably takes precedence. Administering sublingual nitroglycerin (Choice C) is appropriate but should come after ensuring the client's comfort. Applying nasal oxygen (Choice D) can be beneficial, but it should not be the first action; assisting the client to sit or lie down is the initial priority.
2. It has been generally accepted that the percentage of total daily calories supplied by fats should be no more than:
- A. 10% to 15%.
- B. 10% to 35%.
- C. 20% to 35%.
- D. 40% to 55%.
Correct answer: C
Rationale: The recommended fat intake is between 20% to 35% of total daily calories. This range is considered optimal for maintaining a healthy diet. Choice A (10% to 15%) is too low and might not provide enough essential fats for the body. Choice B (10% to 35%) includes an upper limit that exceeds the generally accepted range. Choice D (40% to 55%) suggests a fat intake that is higher than what is recommended, which could lead to health issues if consumed regularly.
3. After absorption, the end products of carbohydrate and protein digestion enter the:
- A. enterohepatic circulation.
- B. gastrointestinal circulation.
- C. common bile duct.
- D. portal blood system.
Correct answer: D
Rationale: The correct answer is D: portal blood system. After absorption, carbohydrates and proteins are transported via the portal blood system to the liver for further processing and distribution to the rest of the body. Choices A, B, and C are incorrect. Enterohepatic circulation refers to the recycling of compounds between the liver and the intestines, not the direct route for absorbed nutrients. Gastrointestinal circulation is a vague and non-specific term, not specifically related to the transport of absorbed nutrients. The common bile duct is involved in transporting bile from the liver and gallbladder to the small intestine, not the end products of carbohydrate and protein digestion.
4. A nurse is preparing to perform closed intermittent bladder irrigation for a client following a transurethral resection of the prostate (TURP). Which of the following actions is appropriate by the nurse?
- A. Aspirate the irrigation solution from the bladder
- B. Insert the tip of the irrigation syringe into the catheter opening
- C. Apply sterile gloves
- D. Open the flow clamp to the irrigating fluid infusion tubing
Correct answer: C
Rationale: The correct action for the nurse to take before performing a closed intermittent bladder irrigation is to apply sterile gloves. Sterile gloves help maintain asepsis, reduce the risk of infection, and ensure patient safety during the procedure. Aspirating the irrigation solution from the bladder (Choice A) is not a standard step in closed intermittent bladder irrigation. Inserting the tip of the irrigation syringe into the catheter opening (Choice B) can introduce contaminants into the system. Opening the flow clamp to the irrigating fluid infusion tubing (Choice D) should only be done after ensuring all equipment is ready and the nurse is gloved to maintain sterility.
5. What are the key interventions in managing a patient with diabetic ketoacidosis (DKA)?
- A. Administer insulin and fluids
- B. Administer oral hypoglycemics
- C. Administer glucagon
- D. Administer insulin and monitor blood glucose
Correct answer: A
Rationale: The correct intervention in managing a patient with diabetic ketoacidosis (DKA) is to administer insulin and fluids. Insulin is crucial to correct hyperglycemia, while fluids are important to address dehydration. Administering oral hypoglycemics (Choice B) is not appropriate in the management of DKA as the patient may not be able to absorb oral medications due to gastrointestinal issues. Glucagon (Choice C) is not indicated in the treatment of DKA. Although monitoring blood glucose (Choice D) is important, it is not the sole key intervention for managing DKA; administering insulin and fluids are the primary interventions.
