A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?
- A. ST depression
- B. Inverted T wave
- C. Prominent U wave
- D. Tall peaked T waves
Correct Answer: D
Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

Who should document care?
- A. The LPNs should document the care that they provided and the care that was given by unlicensed assistive staff.
- B. The registered nurse must document all of the care that is provided by the nursing assistants because they are accountable for all care.
- C. All staff members should document all of the care that they have provided.
- D. All staff should document all of the care that they have provided but the registered nurse, as the only independent practitioner, signs it.
Correct Answer: C
Rationale: All staff members should document the care they provided as part of their accountability and to ensure accurate and comprehensive records. In healthcare settings, it is essential for all staff to document the care they deliver for continuity of care and legal purposes. The registered nurse may sign off on the documentation for oversight purposes, but the responsibility of documenting care extends to all staff involved in patient care. Choices A and B incorrectly limit the responsibility to specific roles, while choice D inaccurately suggests that only the registered nurse signs off on the documentation, overlooking the importance of comprehensive documentation by all staff members involved.
The doctor has ordered 500 mg of a medication PO once a day. The tablets on hand are labeled as 1 tablet = 250 mg. How many tablets will you administer to your patient?
- A. 1 Tablet
- B. 2 Tablets
- C. 3 Tablets
- D. 4 Tablets
Correct Answer: B
Rationale: To calculate the number of tablets needed, divide the total dosage prescribed (500 mg) by the dosage per tablet (250 mg per tablet). 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choices A, C, and D are incorrect as they do not accurately reflect the correct calculation based on the provided information.
Alcohol, caffeine, or drugs are high-risk factors that all fall under which broad classification of risk factors?
- A. Social demographic
- B. Environmental
- C. Biophysical
- D. Psychosocial
Correct Answer: D
Rationale: The correct answer is D: Psychosocial. Alcohol, caffeine, or drug use are considered psychosocial risk factors as they are related to individual behavior, lifestyle choices, and social interactions. Choices A, B, and C are incorrect. Social demographic factors (choice A) refer to characteristics of a population such as age, gender, education, income, etc. Environmental factors (choice B) include physical surroundings like air quality, housing conditions, etc. Biophysical factors (choice C) involve biological aspects like genetics, physiology, and health conditions.
A client with a tumor refuses surgery, but the client's partner wants it. Which is the deciding factor in determining if the surgery will be done?
- A. Whether the partner is the client's durable power of attorney for healthcare
- B. Whether the client understands the risk of refusing the procedure
- C. Whether the client's refusal is based on religious belief
- D. Whether the facility's ethical committee reaches a consensus on the case
Correct Answer: B
Rationale: The correct answer is B because the client's understanding of the risks involved in refusing the surgery is crucial in determining the course of action. In this scenario, the client's autonomy and decision-making capacity take precedence. Choice A is not directly relevant to the decision-making process regarding surgery. Choice C, religious beliefs, may influence the decision but should not be the determining factor in this case. Choice D involving the facility's ethical committee is not typically involved in individual patient care decisions.
