1. Which of the following are manifestations of Cushing syndrome?
- A. Truncal obesity with thin extremities.
- B. Enlargement of face, hands, and feet.
- C. Cachexia.
- D. Thick scalp hair.
Correct answer: Truncal obesity with thin extremities.
Rationale: Truncal obesity with thin extremities is a classic manifestation of Cushing syndrome due to the redistribution of fat. Enlargement of face, hands, and feet is seen in conditions like acromegaly, not Cushing syndrome. Cachexia is a state of severe weight loss and muscle wasting, typically seen in conditions like cancer or advanced infections. Thick scalp hair is not typically associated with Cushing syndrome.
2. A 3-year-old child was adopted immediately after birth. The parents have just asked the nurse how they should tell the child that she is adopted. Which guideline concerning adoption should the nurse use in planning a response?
- A. It is best to wait until the child asks about it.
- B. The best time to tell the child is between the ages of 7 and 10 years.
- C. It is not necessary to tell a child who was adopted so young.
- D. Telling the child is an important aspect of their parental responsibilities.
Correct answer: D
Rationale: It is important to tell children about their adoption early, in an age-appropriate manner, as part of building trust and openness in the family relationship.
3. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?
- A. True
- B. False
- C. Not applicable
- D. Not applicable
Correct answer: True
Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.
4. A nurse is caring for several clients with dehydration. The nurse assesses the client with which finding as needing oxygen therapy?
- A. Tenting of skin on the back of the hand
- B. Increased urine osmolarity
- C. Weight loss of 10 pounds
- D. Pulse rate of 115 beats/min
Correct answer: Pulse rate of 115 beats/min
Rationale: The correct answer is the pulse rate of 115 beats/min. A rapid pulse rate is a sign of compensatory mechanisms in response to dehydration, indicating that the body is trying to deliver oxygen more efficiently. Oxygen therapy may be needed to support the increased oxygen demand. Tenting of skin on the back of the hand is a classic sign of dehydration due to decreased skin turgor. Increased urine osmolarity and weight loss are also indicators of dehydration, but they do not directly suggest a need for oxygen therapy.
5. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.
- A. Both the statement and the reason are correct and related.
- B. Both the statement and the reason are correct but are not related.
- C. The statement is correct, but the reason is not correct.
- D. The statement is not correct, but the reason is correct.
Correct answer: A
Rationale: Both the statement and the reason are correct and related. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.
