Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.

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: C

Rationale: The correct answer is C: The need to perform thorough hand hygiene before handling the prosthesis. This is crucial to prevent infection. By washing hands thoroughly, the patient reduces the risk of introducing harmful bacteria or pathogens to the prosthesis, which could lead to infections or other complications. Incorrect Choices: A: The need to limit exposure to bright light - This is not directly related to caring for an ocular prosthesis. B: The need to maintain a low Fowlers position when removing the prosthesis - Positioning is not typically a concern when caring for an ocular prosthesis. D: The need to apply antiviral ointment to the prosthesis daily - Antiviral ointment is not a standard part of ocular prosthesis care unless specifically prescribed by a healthcare provider for a particular reason.

Correct Answer: C

Rationale: The correct answer is C because it includes fiber-rich whole wheat bread, grapes, and walnuts which promote healthy bowel elimination. Whole wheat bread and fruits provide dietary fiber that aids in digestion and prevents constipation. Walnuts are high in omega-3 fatty acids which can also help with bowel regularity. Option A (Broccoli and cheese soup with potato bread) lacks fiber and may cause constipation due to the low fiber content. Option B (Turkey and mashed potatoes with brown gravy) may be low in fiber and high in fat, which can slow down digestion. Option D (Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing) is a healthier choice but may lack sufficient fiber for promoting healthy bowel elimination compared to option C.

Correct Answer: A

Rationale: The correct answer is A: Stop the infusion of magnesium. A magnesium level of 6 mg/dL is above the therapeutic range (4-7 mg/dL) for preeclamptic patients receiving magnesium sulfate. Continuing the infusion can lead to magnesium toxicity, causing respiratory depression, cardiac arrest, and neuromuscular blockade. Stopping the infusion is crucial to prevent further complications. Assessing the patient's respiratory rate (B) and deep tendon reflexes (C) are important, but stopping the infusion takes priority to prevent harm. Notifying the health care provider (D) is important but may delay immediate action to address the high magnesium level.
