A client is admitted to the hospital for medical treatment of pneumonia. What diagnostic test would the nurse examine to help the health care provider to determine the next step in planning care?

Pulse oximetry

Bronchoscopy

Pulmonary function studies

Culture and sensitivity tests of sputum

Answer and Explanation

The Correct Answer is D

A.   While pulse oximetry is important for assessing oxygen saturation and determining if supplemental oxygen is needed, it does not provide specific information about the type of pneumonia or the causative organism. It’s more of a monitoring tool than a diagnostic test to guide treatment planning.
B.   Bronchoscopy can be useful for visualizing the airways and obtaining samples if the pneumonia is severe or complicated (e.g., suspected abscess or obstruction). However, it is not routinely performed for all pneumonia cases and is not the first-line diagnostic test for planning care.
C.   Pulmonary function tests assess lung capacity and airflow but are not directly useful for diagnosing pneumonia or guiding immediate treatment plans. They are more relevant for chronic respiratory conditions such as asthma or COPD.
D.   Sputum culture and sensitivity tests are critical in pneumonia cases as they help identify the specific organism causing the infection and determine the most effective antibiotic treatment. This information is essential for guiding the healthcare provider in planning appropriate and targeted therapy, especially in cases of community-acquired versus hospital-acquired pneumonia.

Correct Answer is B

Explanation

A. This meal includes a hamburger, which is typically high in saturated fat and sodium, especially if it's made from fatty cuts of meat and includes processed cheese or condiments. Steak fries are often high in fat and sodium due to being fried. While the orange is a healthy fruit, the rest of the meal does not align with the DASH diet principles.
B. This meal is a good example of the DASH diet. The turkey provides lean protein, whole wheat bread offers whole grains, and the green beans are a vegetable. The banana adds a serving of fruit. This combination emphasizes a variety of food groups that are encouraged in the DASH diet, making it a balanced and heart-healthy option.
C. Pork sausage is typically high in saturated fat and sodium, which is not aligned with the DASH diet's recommendations to limit these components. Baked beans can be a good source of fiber but may also contain added sugars and sodium depending on how they are prepared. Overall, this meal does not fit well within the DASH diet framework.
D. While enriched cereal can provide essential vitamins and minerals, it may also be high in added sugars, which is discouraged on the DASH diet. Whole milk is higher in saturated fat compared to low-fat or non- fat dairy options recommended by the DASH diet. Therefore, this meal does not fully meet DASH guidelines.

A. Blocks formation of angiotensin II, a potent vasoconstrictor B. Blocks the action, not the formation, of angiotensin C. Relaxes the smooth muscle of the blood vessels. D. Decreases blood vessels ability to contract and cause vasoconstriction.

Correct Answer is C

Explanation

A. This is the mechanism of action of angiotensin-converting enzyme (ACE) inhibitors, not calcium channel blockers. ACE inhibitors work by preventing the formation of angiotensin II, a hormone that causes blood vessels to constrict.
B. Calcium channel blockers do not directly affect angiotensin.
C. This is the correct mechanism of action of calcium channel blockers. By blocking the influx of calcium ions into smooth muscle cells, these medications cause the blood vessels to relax and dilate, lowering blood pressure.
D. Calcium channel blockers work by relaxing the smooth muscle of the blood vessels, which decreases their ability to contract and cause vasoconstriction.
