1. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:
- A. Percussion uses only one hand, while vibration uses both hands
- B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
- C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
- D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation
Correct answer: D
Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.
2. Which of the following amino acids are considered indispensable?
- A. Lysine
- B. Methionine
- C. Tryptophan
- D. Valine
Correct answer: A
Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
3. Each of the following describes the physiologic roles of water, except one. Which is the exception?
- A. Acts as a solvent for chemical reactions.
- B. Maintains stability of body fluids.
- C. Enables transport of nutrients and excretion of waste.
- D. Regulates temperature by pooling as perspiration on skin.
Correct answer: D
Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.
4. A client with chronic kidney disease is being taught about dietary needs by a nurse. Which of the following foods should the nurse identify as being the lowest in phosphorus?
- A. Medium apple
- B. Bran cereal
- C. Scrambled eggs
- D. Ground turkey
Correct answer: A
Rationale: The correct answer is A, a medium apple. Apples are a suitable option for clients with chronic kidney disease as they are low in phosphorus. Bran cereal (choice B), scrambled eggs (choice C), and ground turkey (choice D) are all higher in phosphorus content compared to apples, making them less ideal choices for individuals with chronic kidney disease.
5. Symptoms of irritable bowel syndrome are most likely associated with disturbed defecation, bloating, and _____.
- A. rectal bleeding
- B. abdominal pain
- C. rectal fissures
- D. esophageal paralysis
Correct answer: B
Rationale: Abdominal pain is a common symptom of irritable bowel syndrome (IBS), along with bloating and changes in bowel habits. Rectal bleeding (choice A) is more commonly associated with conditions like inflammatory bowel disease or colorectal cancer. Rectal fissures (choice C) may cause rectal bleeding but are not typically considered a core symptom of IBS. Esophageal paralysis (choice D) is unrelated to the symptoms of IBS, which primarily affect the lower gastrointestinal tract.
