Correct Answer: C

Rationale: The correct answer is C: An inference. When the nurse documents that the client is confused, it is an interpretation or conclusion drawn from the observed behavior or symptoms. Inferences are based on subjective and objective data. Subjective data (choice A) is based on what the client states, while a data cue (choice B) is a piece of information that may lead to an inference but is not the actual interpretation. Primary data (choice D) refers to firsthand information obtained directly from the client, which is not the case here. In this scenario, the nurse is making an inference based on the observed confusion, making choice C the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Ulcerative colitis. Iron therapy can exacerbate gastrointestinal issues, including ulcerative colitis due to its potential to cause irritation and inflammation in the digestive tract. This can lead to worsening symptoms and complications for the client. A: Pregnancy is not a contraindication for iron therapy; in fact, it is commonly prescribed during pregnancy to prevent or treat anemia. C: Asthma is not a contraindication for iron therapy as it does not directly interact with asthma or its treatment. D: Severely impaired liver function is not a direct contraindication for iron therapy, although caution may be needed in such cases due to iron metabolism being affected by liver function.

Correct Answer: A

Rationale: The correct answer is A: Decreased resistance to infection. Lymphocytes are a crucial part of the immune system, responsible for fighting off infections. A decrease in the number of lymphocytes with age leads to a weakened immune response, making individuals more susceptible to infections. - Choice B: Cognitive problems, is not directly related to lymphocyte levels. - Choice C: Urinary incontinence, is not a typical effect of decreased lymphocytes. - Choice D: Decrease in various blood components, is too broad and not specific to the role of lymphocytes in immunity.

Correct Answer: A

Rationale: The correct answer is A: Citrus fruits and green leafy vegetables. Citrus fruits and green leafy vegetables are good sources of Vitamin C and iron, which are essential for individuals with iron deficiency anemia. Vitamin C enhances the absorption of iron from plant-based sources, while green leafy vegetables provide iron. Bananas and nuts (choice B) are not significant sources of iron. Coffee and tea (choice C) can inhibit iron absorption. Dairy products (choice D) are not high in iron and can also inhibit iron absorption. Therefore, choosing citrus fruits and green leafy vegetables indicates understanding of the dietary instructions for managing iron deficiency anemia.

Correct Answer: D

Rationale: The correct answer is D, "Ineffective thermoregulation related to dehydration." The client's high serum glucose level of 618mg/dl indicates severe hyperglycemia, leading to dehydration. The client's hot, dry skin and elevated temperature can be signs of dehydration, impacting the body's ability to regulate temperature. Dehydration can also affect other vital signs, contributing to the elevated heart rate and low blood pressure. Addressing ineffective thermoregulation is crucial as it can lead to further complications. Choices A, B, and C are not the highest priority because addressing dehydration and ineffective thermoregulation takes precedence due to the immediate risk of complications such as heatstroke or hypothermia. Deficient volume, decreased cardiac output, and imbalanced nutrition are important but not as urgent in this scenario.
