1. Which neuromuscular disease is characterized by abnormal chewing and swallowing patterns, tremors of the mandible, lip, and tongue, frequent drooling, and holding food in the mouth for extended periods?
- A. Developmental disabilities
- B. Parkinson's disease
- C. Epilepsy
- D. Diabetes mellitus
Correct answer: B
Rationale: The correct answer is B, Parkinson's disease. Parkinson's disease is characterized by abnormal chewing and swallowing patterns, tremors of the mandible, lip, and tongue, frequent drooling, and difficulties in oral functions like holding food in the mouth. Developmental disabilities (Choice A) do not specifically cause these symptoms related to neuromuscular function. Epilepsy (Choice C) is a neurological disorder characterized by recurrent seizures and does not typically present with the described symptoms. Diabetes mellitus (Choice D) is a metabolic disorder that affects blood sugar regulation and does not directly cause the neuromuscular symptoms mentioned in the question.
2. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
3. Scurvy is caused by a deficiency of which vitamin?
- A. Vitamin A
- B. Vitamin D
- C. Vitamin E
- D. Vitamin K
Correct answer: C
Rationale: Scurvy is caused by a deficiency of vitamin C, not vitamin E. The symptoms of scurvy include spontaneous gingival hemorrhaging, perifollicular petechiae, follicular hyperkeratosis, diarrhea, fatigue, depression, and cessation of bone growth. Vitamin A (Choice A) is important for vision and immune function, Vitamin D (Choice B) is essential for bone health, and Vitamin K (Choice D) is necessary for blood clotting. However, none of these vitamins are associated with scurvy.
4. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?
- A. glucagon
- B. ghrelin
- C. leptin
- D. insulin
Correct answer: C
Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
5. Knowing that for a comatose patient hearing is the last sense to be lost, as Judy’s nurse, what should you do?
- A. Tell her family that probably she can’t hear them
- B. Talk loudly so that Wendy can hear you
- C. Tell her family who are in the room not to talk
- D. Speak softly then hold her hands gently
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
