A client with chronic obstructive pulmonary disease (COPD) reports increased shortness of breath with activity.
Which test should the nurse schedule the client for evaluation of the symptoms?

Lung biopsy.

Spirometry.

Antibody testing.

Sweat test.

Answer and Explanation

The Correct Answer is B

Choice A rationale

A lung biopsy is an invasive procedure that is typically performed to diagnose conditions such as lung cancer or interstitial lung disease. It is not the first-line test for evaluating increased shortness of breath in a client with COPD56.

Choice B rationale

Spirometry is a common, non-invasive test used to assess lung function and is particularly useful in conditions like COPD. It measures the volume and speed of air a person can inhale and exhale, which can help in assessing the severity of COPD56.

Choice C rationale

Antibody testing is typically used to diagnose conditions related to the immune system, such as allergies or autoimmune diseases. It is not typically used to evaluate shortness of breath in a client with COPD56.

Choice D rationale

A sweat test is used to diagnose cystic fibrosis by measuring the amount of salt in a person’s sweat. It is not used to evaluate shortness of breath in a client with COPD56.

Correct Answer is D

Explanation

Choice A rationale

Serum albumin levels can be relevant in assessing nutritional status and the body’s ability to heal wounds. However, they do not directly indicate the presence of infection or purulent drainage.

Choice B rationale

Hematocrit measures the percentage of red blood cells in the blood and is not directly related to the presence of purulent drainage at a burn wound site. Elevated hematocrit may indicate dehydration or hemoconcentration but does not specifically address the issue of wound infection.

Choice C rationale

Serum blood glucose (BG) level is not directly related to the presence of purulent drainage at a burn wound site. Elevated BG levels might be seen in clients with diabetes or as a stress response, but they are not the primary indicator of infection or wound complications.

Choice D rationale

Neutrophil count is a key laboratory value to note when a client with a full-thickness burn has purulent drainage at the wound. An elevated neutrophil count can indicate an infection, which could be the cause of the purulent drainage.

Correct Answer is ["1.32"]

Explanation

Step 1 is to convert the patient’s weight from pounds to kilograms. There are approximately 2.2046 pounds in 1 kilogram. So, the patient’s weight in kilograms is 132 lb ÷ 2.2046 = 59.87 kg.

Step 2 is to calculate the total dose of lorazepam the patient should receive. The prescribed dose is 44 mcg/kg. So, the total dose in micrograms is 44 mcg/kg × 59.87 kg = 2634.28 mcg.

Step 3 is to convert the total dose from micrograms to milligrams. There are 1000 micrograms in 1 milligram. So, the total dose in milligrams is 2634.28 mcg ÷ 1000 = 2.63428 mg.

Step 4 is to calculate the volume of lorazepam solution to administer. The concentration of the solution is 2 mg/mL. So, the volume in milliliters is 2.63428 mg ÷ 2 mg/mL = 1.31714 mL. Therefore, the nurse should administer approximately 1.32 mL of the lorazepam solution, rounding to the nearest hundredth as required.
