Kaplan NCLEX Question of The Day
1. A client admitted with an episode of bleeding esophageal varices is receiving propranolol (Inderal LA). The nurse knows to monitor for?
- A. Hypertension
- B. Hyperkalemia
- C. Bradycardia
- D. Arthralgia
Correct answer: C
Rationale: The correct answer is 'Bradycardia.' Propranolol is a beta-blocking agent used to decrease the heart rate. In the case of bleeding esophageal varices, propranolol is given to reduce the risk of bleeding by keeping the heart rate around 55 beats per minute. Monitoring for bradycardia is essential as the medication's intended effect is to lower the heart rate. Choices A, B, and D are incorrect because propranolol would not typically cause hypertension, hyperkalemia, or arthralgia.
2. While assessing a patient who has undergone a recent CABG, the nurse notices a mole with irregular edges and a bluish color. What should the nurse do next?
- A. Recommend a dermatological consult to the physician.
- B. Note the location of the mole and contact the physician via telephone.
- C. Note the location of the mole and follow-up with the attending physician through the medical record and a phone call.
- D. Remove the mole with a sharp debridement technique, following approval from the charge nurse.
Correct answer: C
Rationale: In this scenario, the nurse should note the location of the mole and follow up with the attending physician through the medical record and a phone call. This action is appropriate because a mole with irregular edges and a bluish color raises concern for melanoma, a type of skin cancer. Recommending a dermatological consult (Choice A) might delay the evaluation and management of the mole. Contacting the physician via telephone (Choice B) may not provide a documented record of the observation. Removing the mole without proper evaluation (Choice D) could be dangerous and is not within the nurse's scope of practice.
3. The nurse is caring for a client receiving warfarin therapy (Coumadin®) following a stroke. The client's PT/INR was completed at 7:00 A.M. prior to the morning meal with an INR reading of 4.0. Which of the following is the nurse's first priority?
- A. Call the physician to request an increase in the Coumadin® dose.
- B. Administer a vitamin K injection IM and notify the physician of the results.
- C. Assess the client for bleeding around the gums or in the stool and notify the physician of the lab results and latest dose of Coumadin®.
- D. Notify the next shift to hold the daily dose of Coumadin® scheduled for 5:00 P.M.
Correct answer: B
Rationale: In a client receiving warfarin therapy with a high INR of 4.0, the nurse's first priority is to administer a vitamin K injection intramuscularly (IM) and notify the physician of the results. An INR of 4.0 indicates excessive anticoagulation, putting the client at risk of bleeding. Vitamin K is the antidote for warfarin overdose and helps to reverse its effects. It is crucial to administer vitamin K promptly to prevent bleeding complications. Calling the physician to request an increase in the Coumadin® dose is inappropriate and dangerous in this situation, as it would further raise the INR. Assessing the client for bleeding and notifying the physician is important but not the first priority when faced with a critically high INR. Holding the daily dose of Coumadin® may be necessary after administering vitamin K, but it is not the primary action needed to address the acute high INR level.
4. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
5. Which of the following can certain foods like broccoli, oranges, dark greens, and dark yellow vegetables help improve?
- A. Vitamin intake
- B. Body functions
- C. Defense mechanisms
- D. Disease cure
Correct answer: C
Rationale: Certain foods like broccoli, oranges, dark greens, and dark yellow vegetables can help improve defense mechanisms by enhancing the immune system and overall health. While these foods can boost defense mechanisms, they are not a cure for diseases, do not balance body functions, and are not intended to solely supplement vitamin intake, which may be necessary in some cases. Therefore, the correct answer is defense mechanisms as these foods strengthen the body's ability to fight off illnesses and maintain health.
