Question 1 of 5

Which of the following is an example of a categorical variable?

Correct Answer: C

Rationale: Categorical variables represent distinct categories or groups without any inherent order or numerical value. Gender fits this definition as it categorizes individuals into distinct groups (male, female). In contrast, age, income, and height are numerical variables that can be ordered or measured quantitatively, making them examples of quantitative variables rather than categorical variables.

Question 2 of 5

A nurse on a medical-surgical unit has accepted a transfer to the intensive care unit (ICU). Prior to transfer, the nurse completes an online critical care and emergency nursing course. The nurse is demonstrating which of the following ethical principles?

Correct Answer: D

Rationale: The correct answer is D: Nonmaleficence. This principle emphasizes the duty to do no harm to the patient. By completing a critical care course, the nurse is ensuring that they have the necessary knowledge and skills to provide safe and competent care in the ICU, thereby upholding the principle of nonmaleficence. Veracity (A) relates to truth-telling, Autonomy (B) refers to respecting the patient's right to make decisions, and Fidelity (C) pertains to being faithful and keeping promises, none of which directly apply to the nurse's situation of transferring to the ICU after completing a critical care course.

Question 3 of 5

Sudden sleep

Correct Answer: A

Rationale: Step-by-step rationale for why answer A (Narcolepsy) is correct: 1. Narcolepsy is a neurological disorder characterized by sudden and uncontrollable episodes of sleep. 2. People with narcolepsy experience excessive daytime sleepiness and may fall asleep at inappropriate times. 3. The sudden onset of sleep is a hallmark symptom of narcolepsy. 4. Hypersomnia (choice B) is excessive daytime sleepiness but does not involve sudden sleep attacks like narcolepsy. Summary of why other choices are incorrect: - Choice B (Hypersomnia) is incorrect because it does not involve sudden sleep attacks, which is a defining symptom of narcolepsy.

Question 4 of 5

Mother under NSD

Correct Answer: A

Rationale: The correct answer is A: Straight catheter. In a mother undergoing a normal spontaneous delivery (NSD), a straight catheter is used for intermittent bladder emptying to prevent urinary retention without causing unnecessary trauma or infection. This type of catheter allows for short-term catheterization and reduces the risk of catheter-associated complications compared to indwelling catheters (Choice B). Option C and D are left blank as they are irrelevant choices.

Question 5 of 5

Sexuality

Correct Answer: A

Rationale: The correct answer is A because sexuality refers to a person's sexual orientation, behaviors, and identity, not just based on gender but also encompassing aspects such as attraction, expression, and relationships. Choice B is incorrect as it narrowly defines sexuality as solely focused on opposite-sex physical activity leading to conception, which does not consider all aspects of human sexuality. Choices C and D are blank and do not provide any information, making them incorrect by default. In summary, choice A is correct as it accurately reflects the comprehensive nature of human sexuality, while the other choices are incorrect due to their limited or lack of understanding of the concept.
