A nurse is caring for a group of clients. The nurse should obtain a blood pressure reading using only the left extremity from which of the following clients?

Desmopressin is a synthetic form of antidiuretic hormone (ADH), which regulates water balance in the body. Diabetes insipidus is a condition caused by a deficiency or resistance to ADH, resulting in excessive urination and thirst. Desmopressin helps reduce urine output and prevent dehydration by mimicking the action of ADH on the kidneys. Lithium is a mood stabilizer that can cause nephrogenic diabetes insipidus by interfering with the response of the kidneys to ADH. Regular insulin is used to treat diabetes mellitus, not diabetes insipidus, as it lowers blood glucose levels by facilitating its uptake into cells.

Furosemide is a diuretic that increases urine output and can worsen dehydration in clients with diabetes insipidus.

An acute asthma attack is a sudden worsening of asthma symptoms, such as coughing, wheezing, tightness in the chest, and difficulty breathing. These symptoms happen because the airways in the lungs become narrow, irritated, swollen, and produce excess mucus.

An asthma attack can be triggered by various factors, such as allergic reactions, respiratory infections, tobacco smoke, cold air, and exercise. These triggers cause the immune system to react and release chemicals that cause inflammation and constriction of the airways.

Based on this information, the best answer to the question is a. Inability to exhale retained carbon dioxide. This is because during an asthma attack, the narrowed airways make it harder to exhale the air from the lungs, which leads to a buildup of carbon dioxide in the blood. This can worsen the symptoms and cause acidosis, a condition where the blood becomes too acidic.

The other options are not correct because:

b. Acute loss of alveolar elasticity is not a cause of asthma attacks, but a consequence of chronic obstructive pulmonary disease (COPD), a different lung condition that involves damage to the alveoli, the tiny air sacs in the lungs.
c. Decreased responsiveness of airways to allergens is not a cause of asthma attacks, but a goal of asthma treatment. Asthma medications aim to reduce the sensitivity and inflammation of the airways to prevent or reduce the frequency and severity of asthma attacks.
d. Suppressed bronchiolar inflammatory response is not a cause of asthma attacks, but a potential side effect of some asthma medications, such as corticosteroids. These drugs can suppress the immune system and increase the risk of infections in the airways.
