1. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

2. A client newly diagnosed with hypertension is receiving teaching about the Mediterranean diet from a nurse. Which of the following statements by the client indicates a need for further teaching?

• A. I will limit my intake of red meat to twice weekly.
• B. I can have dairy in moderate portions daily.
• C. I can have fish two times a week.
• D. I can drink wine in moderation.

Correct answer: D

Rationale: The correct answer is D. Patients with hypertension should be advised to limit alcohol consumption, including wine, to help manage their blood pressure. Choices A, B, and C are all consistent with the Mediterranean diet and are appropriate for a client with hypertension. Reducing red meat intake, consuming dairy in moderate portions, and having fish regularly align with the principles of this heart-healthy eating pattern.

3. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

4. During the phallic stage, with which parent must the child identify?

• A. The same-sex parent
• B. The opposite-sex parent
• C. The mother or the primary caregiver
• D. Both parents

Correct answer: A

Rationale: According to Freud's psychosexual development theory, during the phallic stage (approximately ages 3 to 6), the child starts to identify with the parent of the same sex. This identification is a crucial part of the child's development and is believed to influence their adult behavior. The process involves the child adopting the characteristics, attitudes, and values of the same-sex parent. Choice B, C, and D are incorrect as they do not align with Freud's theory of the phallic stage of psychosexual development.

5. Can soluble fibers be fermented by gut bacteria?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.
