1. A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?
- A. ATNR reflex
- B. Startle reflex
- C. Grasping reflex
- D. Moro reflex
Correct answer: Moro reflex
Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.
2. Which of the following is not a function of parathyroid hormone?
- A. moving calcium from bones to the bloodstream
- B. inhibiting renal tubular reabsorption of phosphorus
- C. promoting renal tubular reabsorption of calcium
- D. enhancing renal production of vitamin D metabolites
Correct answer: inhibiting renal tubular reabsorption of phosphorus
Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.
3. How can a diet high in fiber content benefit an individual?
- A. aid in rapid weight loss.
- B. reduce diabetic ketoacidosis.
- C. lower cholesterol.
- D. reduce the requirement for folate.
Correct answer: lower cholesterol.
Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.
4. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?
- A. Hypocalcemia
- B. Hypomagnesemia
- C. Hyponatremia
- D. Hypokalemia
Correct answer: Hypokalemia
Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.
5. As part of the teaching plan for a client with type I diabetes mellitus, the nurse should include that carbohydrate needs might increase when:
- A. an infection is present.
- B. there is an emotional upset.
- C. a large meal is eaten.
- D. active exercise is performed.
Correct answer: active exercise is performed.
Rationale: During active exercise, insulin sensitivity increases, leading to lower blood glucose levels. To balance the effect of increased insulin sensitivity, additional carbohydrates might be needed. The other choices are incorrect because: A) an infection typically raises blood glucose levels rather than increasing the need for carbohydrates; B) emotional upset can impact blood glucose but does not directly affect carbohydrate needs; C) while a large meal can raise blood glucose levels, it does not necessarily mean an increase in carbohydrate needs.
