The patient complaints of dyspnea and the nurse is concerned the patient may need oxygen. What assessment will the nurse perform to determine if the patient needs supplemental oxygen?

Auscultate breath sounds.

Observe chest expansion

Measure capillary refill

Measure oxygen saturation

Answer and Explanation

The Correct Answer is D

A.   Auscultating breath sounds can provide valuable information about the presence of wheezing, crackles, or diminished breath sounds, which may indicate respiratory issues. However, while this assessment is important for understanding the underlying cause of dyspnea, it does not directly measure the patient's oxygenation status.
B.   Observing chest expansion can help the nurse assess the mechanics of breathing and whether there are any restrictions in lung expansion. While this assessment is useful, it does not provide a clear indication of the patient's oxygen saturation levels or immediate need for supplemental oxygen.
C.   Measuring capillary refill can give insights into peripheral perfusion and circulation, which can be affected by oxygenation. However, it is not the most direct or specific assessment for determining the need for supplemental oxygen in a patient with dyspnea.
D.   Measuring oxygen saturation (using a pulse oximeter) provides a direct and objective assessment of the patient's oxygenation status. Normal oxygen saturation levels typically range from 95% to 100%. If the oxygen saturation is below the acceptable range (usually less than 92% in many clinical settings), this would indicate the need for supplemental oxygen.

Correct Answer is C

Explanation

A. ACE inhibitors can cause a dry cough in some patients, but this is not typically a severe issue for patients with asthma.
B. These medications do not have a significant impact on respiratory function and are generally safe for patients with asthma.
C. Beta-blockers can constrict the airways, making them less suitable for patients with asthma. They can worsen asthma symptoms, trigger bronchospasm, and reduce the effectiveness of beta-agonist bronchodilators.
D. Thiazide diuretics do not have a significant impact on respiratory function and are generally safe for patients with asthma.

A. Any known allergies to drugs or environmental factors. B. Poor oral hygiene. C. Dietary history indicating ingestion of sugary foods D. Use of non-steroidal anti-inflammatory drugs (NSAID's).

Correct Answer is D

Explanation

A. While allergies can impact a patient's overall health, they are not directly related to the development of peptic ulcer disease. Allergies do not contribute to the mechanisms that cause ulcers, such as increased stomach acid or mucosal damage.
B. Poor oral hygiene can lead to dental problems and infections, but it is not a recognized risk factor for peptic ulcer disease. The main causes of peptic ulcers are related to factors that affect the stomach lining, such as certain medications, lifestyle choices, and infections.
C. While diet can influence gastrointestinal health, sugary foods are not a primary risk factor for peptic ulcers. The role of sugar in ulcer development is not well established compared to other factors, such as the use of certain medications or the presence of H. pylori infection.
D. This statement is correct and is a significant risk factor for developing peptic ulcer disease. NSAIDs can cause irritation of the stomach lining and inhibit the production of protective mucus, leading to ulcer formation. Chronic use of NSAIDs is one of the most common causes of peptic ulcers.
