After initiating a steroid nebulizer treatment for a client with asthma in respiratory distress, which intervention is most important for the nurse to implement?
Monitor pulse oximetry every 2 hours.
Teach proper use of a rescue inhaler.
Elevate the head of bed to 90 degrees.
Determine exposure to asthmatic triggers.
The Correct Answer is C
Choice A reason: This is incorrect because monitoring pulse oximetry every 2 hours is not a sufficient or timely intervention for the nurse to implement. Pulse oximetry is a noninvasive method of measuring the oxygen saturation of hemoglobin in the blood. Normal oxygen saturation is 95% to 100%, while hypoxemia is less than 90%. However, pulse oximetry may not reflect the severity of respiratory distress or the effectiveness of nebulizer treatment in a client with asthma. Moreover, monitoring pulse oximetry every 2 hours is too infrequent for a client who is in acute respiratory distress and needs more frequent assessment and intervention.
Choice B reason: This is incorrect because teaching proper use of a rescue inhaler is not a priority or relevant intervention for the nurse to implement. A rescue inhaler is a type of short-acting bronchodilator that can be used to relieve acute asthma symptoms by relaxing the smooth muscles of the airways and improving airflow. However, teaching proper use of a rescue inhaler is not an urgent action for a client who is already receiving nebulizer treatment, which delivers a higher dose of medication directly to the lungs. Moreover, teaching proper use of a rescue inhaler is not appropriate for a client who is in respiratory distress and may not be able to focus or retain information.
Choice C reason: This is correct because elevating the head of bed to 90 degrees is the most important intervention for the nurse to implement. Elevating the head of bed to 90 degrees can help improve breathing and oxygenation by reducing pressure on the diaphragm and chest wall, increasing lung expansion and ventilation, and facilitating expectoration of mucus. This can enhance the effects of nebulizer treatment and reduce respiratory distress in a client with asthma.
Choice D reason: This is incorrect because determining exposure to asthmatic triggers is not an immediate or helpful intervention for the nurse to implement. Asthmatic triggers are substances or factors that can cause or worsen asthma symptoms by inducing inflammation or constriction of the airways. Examples of asthmatic triggers include allergens, irritants, infections, exercise, stress, or weather changes. However, determining exposure to asthmatic triggers is not a priority action for a client who is in respiratory distress and needs more urgent interventions to improve breathing and oxygenation. Moreover, determining exposure to asthmatic triggers may not change the management or outcome of an acute asthma attack that has already occurred.

Correct Answer is B
Explanation
Choice A reason: The humoral immune response is mediated by B cells that produce antibodies against specific antigens. However, this response is not the main problem in AIDS, because B cells are not directly affected by the human immunodeficiency virus (HIV) that causes AIDS. Therefore, this choice is incorrect.
Choice B reason: The cellular immune response is mediated by T lymphocytes that activate other immune cells, such as macrophages, to destroy infected or abnormal cells. This response is the main problem in AIDS, because HIV infects and destroys CD4+ T cells, which are essential for coordinating the cellular immunity. As a result, the client becomes susceptible to opportunistic infections, such as Pneumocystis jiroveci pneumonia. Therefore, this choice is correct.
Choice C reason: Bone marrow suppression of white blood cells can cause immunodeficiency, but it is not the primary cause of AIDS. Bone marrow suppression can occur as a side effect of some drugs or treatments, such as chemotherapy or radiation therapy, but it is not directly caused by HIV. Therefore, this choice is incorrect.
Choice D reason: Exposure to multiple environmental infectious agents can challenge the immune system, but it does not necessarily cause it to fail. The immune system can adapt and respond to different pathogens, unless it is compromised by an underlying condition, such as AIDS. Therefore, this choice is incorrect.
Correct Answer is A
Explanation
Choice A reason: Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.
Choice B reason: Fremitus over the chest wall is a sign of increased vibration or air movement in the lungs, which can indicate pneumonia, bronchitis, or pleural effusion. These are not related to SIADH, but may be complications of head injury or fluid overload.
Choice C reason: Serum sodium of 150 mEq/L (150 mmol/L) is a sign of hypernatremia, which is a high level of sodium in the blood. This is the opposite of what happens in SIADH, where sodium levels are low due to dilution by excess water.
Choice D reason: Urine specific gravity of 1.004 is a sign of diluted urine, which indicates low concentration of solutes in the urine. This is also the opposite of what happens in SIADH, where urine is concentrated and has a high specific gravity.
