1. What term is used to refer to generalized wasting of body tissues and malnutrition?
- A. Entropion
- B. Confabulation
- C. Induration
- D. Cachexia
Correct answer: D
Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.
2. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?
- A. Pituitary
- B. Pineal
- C. Pancreas
- D. Hypothalamus
Correct answer: B
Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
3. A nurse is caring for newborn infants in a nursery when a man enters the area to take his baby back to the room. The man does not have an identification bracelet, and the nurse does not recognize him. What is the next action of the nurse?
- A. Call security and ask them to escort the man out of the nursery
- B. Ask the man to wait and check the infant's chart
- C. Ask the man to return to his room and bring an identification band
- D. Allow the man to take the baby to his room
Correct answer: C
Rationale: The safety of infants in newborn nurseries is maintained by requiring parents to wear identification bracelets to identify themselves as the rightful parents. This practice minimizes the risk of mistakenly allowing an unauthorized individual to take a baby. In this scenario, since the nurse does not recognize the man and he lacks an identification bracelet, the appropriate action is to ask him to return to his room and bring the identification band. This step ensures the proper identity verification before allowing the man to take the baby. Calling security without first verifying the man's identity may escalate the situation unnecessarily. Checking the infant's chart alone does not confirm the man's identity. Allowing the man to take the baby without proper verification poses a safety risk to the infant.
4. Which of the following statements best describes footdrop?
- A. The foot is permanently fixed in the dorsiflexion position
- B. The foot is permanently fixed in the plantar flexion position
- C. The toes of the foot are permanently fanned
- D. The heel of the foot is permanently rotated outward
Correct answer: B
Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.
5. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?
- A. Electrocardiogram
- B. Bell of the stethoscope
- C. Diaphragm of the stethoscope
- D. Palpation with the nurse's palm of the hand
Correct answer: B
Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.
