Which assessment action will help the nurse determine if an obese patient has metabolic syndrome?
- A. Take the patient's apical pulse.
- B. Check the patient's blood pressure.
- C. Ask the patient about dietary intake.
- D. Dipstick the patient's urine for protein.
Correct Answer: B
Rationale: The correct answer is B: Check the patient's blood pressure. Monitoring blood pressure is crucial in determining if an obese patient has metabolic syndrome, as high blood pressure is one of the key criteria for diagnosing metabolic syndrome. Elevated blood pressure is a common feature of metabolic syndrome and is linked to other risk factors such as obesity, insulin resistance, and dyslipidemia. By checking the patient's blood pressure, the nurse can assess if the patient meets the criteria for metabolic syndrome.
Choice A (Take the patient's apical pulse) is not directly related to diagnosing metabolic syndrome. Choice C (Ask the patient about dietary intake) may provide important information but does not specifically help in diagnosing metabolic syndrome. Choice D (Dipstick the patient's urine for protein) is not a relevant assessment for determining metabolic syndrome.

Which adult should the nurse plan to teach about risks associated with obesity?
- A. Man who has a BMI of 18 kg/m2
- B. Man with a 42 in waist and 44 in hips
- C. Woman who has a body mass index (BMI) of 24 kg/m2
- D. Woman with a waist circumference of 34 inches (86 cm)
Correct Answer: B
Rationale: The correct answer is B because a waist circumference of 42 inches in men signifies abdominal obesity, which is a significant risk factor for health issues related to obesity. A high waist circumference indicates excess visceral fat, which is linked to heart disease and other health problems.
Choice A is incorrect because a BMI of 18 kg/m2 indicates underweight, not obesity.
Choice C is incorrect because a BMI of 24 kg/m2 falls within the healthy weight range, not indicating obesity.
Choice D is incorrect because a waist circumference of 34 inches in women is considered normal, not indicative of obesity.
Which part of a tooth most closely resembles bone tissue?
- A. enamel
- B. cementum
- C. dentin
- D. gingiva
Correct Answer: C
Rationale: The correct answer is C: dentin. Dentin is the part of the tooth that closely resembles bone tissue because it is a hard, dense tissue similar to bone in composition and structure, providing support and protection to the tooth. Dentin is located beneath the enamel and cementum, forming the bulk of the tooth structure. Enamel (choice A) is the hardest tissue in the body but is not similar to bone tissue in composition. Cementum (choice B) is a hard tissue covering the roots of teeth but is not as similar to bone tissue as dentin. Gingiva (choice D) is the soft tissue that surrounds the teeth and is not similar to bone tissue.
A nurse is caring for a client who is receiving total parenteral nutrition (TPN). The nurse notices that the solution bag is almost empty and there is not another bag of TPN to administer. Which of the following IV solutions should the nurse administer until the next bag of TPN solution is available?
- A. 10% dextrose in water (D10W)
- B. 0.45% sodium chloride (0.45% NaCl)
- C. Lactated Ringer's solution
- D. 5% dextrose in lactated Ringer's solution (D5LR)
Correct Answer: A
Rationale: The correct answer is A: 10% dextrose in water (D10W). When a TPN bag is almost empty, abruptly stopping it can lead to hypoglycemia. Administering D10W provides a temporary source of glucose to prevent this. D10W is a hypertonic solution that delivers a high concentration of dextrose for energy. Option B (0.45% NaCl) is hypotonic and lacks the necessary glucose content. Option C (Lactated Ringer's solution) does not contain glucose, and option D (D5LR) contains lactate, which may not be suitable for all patients. Administering D10W is the most appropriate choice to prevent hypoglycemia until the next bag of TPN is available.
The nurse explains that the older adult is prone to digestive disorders related to which age-related change?
- A. Decreased hydrochloric acid
- B. Increased enzyme levels
- C. Inadequate chewing
- D. Diminished intestinal motility
Correct Answer: A
Rationale: The correct answer is A: Decreased hydrochloric acid. As people age, there is a natural decline in hydrochloric acid production in the stomach, leading to decreased digestion and absorption of nutrients. This can result in digestive disorders such as malabsorption. Increased enzyme levels (B) would actually be beneficial for digestion. Inadequate chewing (C) can lead to issues like choking but is not specifically related to age. Diminished intestinal motility (D) can occur with age but is not directly linked to digestive disorders in older adults.
Katrina is diagnosed with lactose intolerance. To avoid complications with lack of calcium in the diet, which food should be included in the diet?
- A. Fruit
- B. Whole grains
- C. Milk and cheese products
- D. Dark green, leafy vegetables
Correct Answer: D
Rationale: The correct answer is D: Dark green, leafy vegetables. Dark green, leafy vegetables are a good source of calcium and can help Katrina meet her calcium needs without consuming milk and cheese products. Since Katrina is lactose intolerant, consuming milk and cheese products can lead to gastrointestinal issues due to the inability to digest lactose. Fruits and whole grains do not provide significant amounts of calcium compared to dark green, leafy vegetables. Therefore, including dark green, leafy vegetables in the diet is the best option to prevent complications from lack of calcium intake.
