A nurse in a mental health clinic receives a request from a client who is undergoing psychotherapy to obtain a copy of the therapist’s notes.

A. BP 150/92 mm Hg:

• This blood pressure reading is elevated and not a therapeutic effect of magnesium sulfate. In the context of preeclampsia, the goal is usually to lower blood pressure to prevent complications.

B. Pulse rate 100/min:

• The pulse rate of 100/min is not a specific therapeutic effect of magnesium sulfate. However, magnesium sulfate may cause a decrease in heart rate, so monitoring for bradycardia would be important.

C. Flushed face:

• A flushed face is not a specific therapeutic effect of magnesium sulfate. Facial flushing may be associated with other factors, but it is not a primary consideration when monitoring the effectiveness of magnesium sulfate in the context of preeclampsia.

D. Negative clonus:

• Negative clonus is the correct therapeutic effect to monitor. Clonus refers to a series of involuntary, rhythmic, and repetitive muscle contractions and relaxations. In the context of magnesium sulfate administration for preeclampsia, negative clonus (the absence of abnormal reflexes) is a sign that the magnesium levels are within the therapeutic range, helping to prevent seizures.

The correct answer is B.

Choice A reason: Completing oral hygiene is important for overall health, especially for individuals with cystic fibrosis, as they are at a higher risk for dental problems due to thick mucus that can harbor bacteria. However, oral hygiene does not have a direct impact on the effectiveness of postural drainage. Postural drainage is a technique used to clear mucus from the lungs, and while maintaining oral hygiene is beneficial, it is not a prerequisite for this procedure.

Choice B reason: Using a bronchodilator, such as an ibuterol inhaler, is recommended before postural drainage because it helps to open the airways, making the procedure more effective. Bronchodilators work by relaxing the muscles around the airways, which can become constricted in conditions like cystic fibrosis. This relaxation allows for easier clearance of mucus during postural drainage.

Choice C reason: Pancrelipase is an enzyme supplement used to aid digestion in patients with cystic fibrosis, who often have pancreatic insufficiency. While taking pancrelipase is crucial for nutrient absorption, it is not specifically related to the respiratory treatment of postural drainage. Therefore, it is not necessary to take pancrelipase immediately before this procedure.

Choice D reason: Eating a meal before postural drainage is not recommended. The procedure involves placing the body in positions that facilitate the drainage of mucus from the lungs due to gravity. Having a full stomach can cause discomfort, increase the risk of vomiting, and may hinder the effectiveness of the drainage. It is best to perform postural drainage when the stomach is empty, either before meals or at least 1.5 hours after eating.
