A pregnant patient asks the nurse if she can take antihistamines for seasonal allergies during her pregnancy. What will the nurse tell the patient?
The margin of safety for antihistamines is clearly understood for pregnant patients
Second-generation antihistamines are safer than first-generation antihistamines
Antihistamines should not be taken during pregnancy but may be taken when breastfeeding
Antihistamines are contraindicated during the third trimester of pregnancy
The Correct Answer is B
The nurse will tell the patient that second-generation antihistamines are generally considered safer than first-generation antihistamines during pregnancy. While the safety of medications during pregnancy is a complex topic and individualized recommendations should be obtained from a healthcare provider, second-generation antihistamines such as loratadine (Claritin) and cetirizine (Zyrtec) are often preferred over first-generation antihistamines like diphenhydramine (Benadryl) due to their lower potential for sedation and other side effects. However, it is still important for the patient to consult with her healthcare provider for personalized advice on medication use during pregnancy.

Correct Answer is C
Explanation
When using an albuterol inhaler, it is important for the client to take a slow and deep inhalation while releasing the medication from the inhaler. After inhaling the medication, holding the breath for about 10 seconds allows the medication to reach deep into the airways and maximize its effectiveness.
The other actions mentioned are not correct:
A. Waiting 10 minutes between inhalations: Albuterol inhalers are typically used as a quick-relief medication for acute symptoms, and waiting 10 minutes between inhalations may not provide immediate relief when needed. The specific instructions on the frequency of inhalations should be provided by the healthcare provider.
B. Taking a quick inhalation while releasing the medication from the inhaler: It is important to take a slow and deep inhalation while releasing the medication to ensure that the medication reaches the lungs effectively. Taking a quick inhalation may result in less effective delivery of the medication.
D. Exhaling as the medication is released from the inhaler: It is important to exhale fully before using the inhaler to ensure that the medication is inhaled deeply into the lungs. Exhaling while releasing the medication can interfere with the proper inhalation technique.
Correct Answer is C
Explanation
The sympathetic nervous system postganglionic neurons primarily release norepinephrine as their neurotransmitter. These neurons are part of the autonomic nervous system and are responsible for coordinating the body's "fight or flight" response to stress or danger.
Norepinephrine acts as a neurotransmitter at the postganglionic synapses and binds to adrenergic receptors in the target tissues, mediating the physiological responses associated with sympathetic activation.
While acetylcholine is the primary neurotransmitter released by the preganglionic neurons of the sympathetic nervous system, it is not the neurotransmitter released by postganglionic neurons. Epinephrine (also known as adrenaline) is released into the bloodstream by the adrenal medulla and acts as a hormone, not a neurotransmitter. Arginine is an amino acid and is not directly involved in the neurotransmission of the sympathetic nervous system.
