test bank foundations of nursing

Correct Answer: C

Rationale: The correct answer is C: Eggs and wheat. This is because eggs and wheat are common food allergens in children. Eggs contain proteins that can trigger allergic reactions, while wheat contains gluten, a common allergen. Citrus fruits and rice (choice A) are not common allergens. Root vegetables and tomatoes (choice B) are also less likely to cause allergies. Hard cheeses and vegetable oils (choice D) are not commonly associated with food allergies in children. Therefore, informing the parents about eggs and wheat as common allergens is crucial for the child's testing and management of food allergies.

Correct Answer: B

Rationale: The correct answer is B: Look at the patient when talking. This is important because maintaining eye contact shows respect, builds trust, and enhances communication with the patient. By looking at the patient, the nurse can also observe nonverbal cues and ensure the patient is engaged in the conversation. Choice A: Using long sentences can be overwhelming for a patient who may not understand the language, leading to miscommunication. Choice C: Using breaks in sentences may help the interpreter better convey the message, but looking at the patient is more essential for effective communication. Choice D: Looking at only nonverbal behaviors neglects the importance of eye contact and direct communication with the patient.

Correct Answer: C

Rationale: The correct answer is C: anticonvulsant. Magnesium sulfate is used in the treatment of preeclampsia to prevent seizures, making it an anticonvulsant. It works by reducing neuromuscular excitability and stabilizing nerve cell membranes. Choice A (diuretic) is incorrect because magnesium sulfate does not primarily promote diuresis. Choice B (tocolytic) is incorrect as it does not inhibit uterine contractions. Choice D (antihypertensive) is incorrect because although magnesium sulfate can help lower blood pressure in preeclampsia, its primary indication in this case is for seizure prophylaxis.

Correct Answer: D

Rationale: Correct Answer: D - Proper hand hygiene techniques Rationale: 1. Clostridium difficile is mainly spread through contact with contaminated surfaces. 2. Proper hand hygiene is the most effective way to prevent the spread of bacteria. 3. Hand hygiene removes bacteria from hands, reducing the risk of transmission. 4. Appropriate disposal (A) is important but doesn't directly prevent spread. Monthly in-services (B) and mandatory cultures (C) are not as effective as hand hygiene in preventing transmission.

Correct Answer: B

Rationale: The correct answer is B: Malignant cells contain proteins called tumor-specific antigens. Tumor-specific antigens are unique to cancer cells and are not found in normal cells. This characteristic distinguishes cancer cells from normal cells and is important in cancer detection and treatment. A: Malignant cells do not necessarily contain more fibronectin than normal body cells. Fibronectin is a glycoprotein found in the extracellular matrix and is not a defining characteristic of cancer cells. C: Chromosomes in cancer cells are actually more prone to instability and mutations compared to normal cells, making them less durable and stable. D: The nuclei of cancer cells can vary in size and shape, with irregularities often seen, rather than being unusually large and regularly shaped.
