1. 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.
2. A healthcare provider is assessing a client who has a stage III pressure ulcer that is healing poorly. The provider should identify that which of the following vitamin deficiencies increases the client’s risk for delayed wound healing?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin E
- D. Vitamin B6
Correct answer: A
Rationale: Corrected Rationale: Vitamin C deficiency can impair collagen synthesis and delay wound healing, making it crucial for recovery from pressure ulcers. Incorrect Rationales: - Vitamin D deficiency is associated with bone health, not specifically wound healing. - Vitamin E deficiency can lead to neurological and immune system issues but is not directly linked to delayed wound healing. - Vitamin B6 deficiency can cause skin rashes and neurological symptoms but is not a primary factor in delayed wound healing.
3. A community health nurse is conducting a class on what to expect during pregnancy. What instruction should the nurse include on weight gain?
- A. Failure to obtain the required weight gain during pregnancy will increase the risk of preterm birth.
- B. An obese client should not gain as much weight as a client with a normal body mass index.
- C. A client with a normal body mass index should plan on gaining 50 pounds.
- D. Clients do not need to eat for two when they are pregnant.
Correct answer: A
Rationale: Adequate weight gain during pregnancy is essential as failure to obtain the required weight gain can increase the risk of preterm birth. Choice B is incorrect because it is important for obese clients to gain an appropriate amount of weight during pregnancy, not the same as those with a normal body mass index. Choice C is incorrect as gaining 50 pounds for a client with a normal body mass index is excessive. Choice D is incorrect as the common saying 'eating for two' during pregnancy is a misconception; pregnant individuals do not need to double their caloric intake.
4. Which of the following is the most important risk factor for development of Chronic Obstructive Pulmonary Disease?
- A. Cigarette smoking
- B. Occupational exposure
- C. Air pollution
- D. Genetic abnormalities
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.
5. Which mineral is a principal component of cell membranes?
- A. phosphorus
- B. magnesium
- C. iron
- D. iodine
Correct answer: A
Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
