A cold is a self-limiting viral infection most commonly caused by Rhinovirus
True
False
The Correct Answer is A
The common cold is a self-limiting upper respiratory tract infection, meaning it typically resolves without specific medical treatment. It is most commonly caused by rhinoviruses, which are highly contagious and spread through respiratory droplets and contact with contaminated surfaces. Symptoms such as nasal congestion, sore throat, cough, and mild fever usually resolve within 7 to 10 days as the immune system clears the virus. Management is primarily supportive, including rest, hydration, and symptom relief, rather than antiviral therapy.

Correct Answer is A
Explanation
A. The patient should not take both of these together because it is a therapeutic duplication: Both Excedrin PM and Excedrin Migraine contain acetaminophen and sometimes other overlapping ingredients such as caffeine or diphenhydramine. Taking them together increases the risk of exceeding safe acetaminophen limits, leading to hepatotoxicity, and may result in excessive sedation from diphenhydramine.
B. The patient should not take both of these together, they cancel each other out: There is no evidence that these medications negate each other’s effects. Both are intended for pain relief, and taking them together does not reduce their efficacy, it increases risk of toxicity.
C. The patient can take both of these together, but there is a theoretical drug interaction: While drug interactions are a consideration, the primary issue here is overlapping active ingredients, which constitutes direct therapeutic duplication rather than a theoretical interaction.
D. The patient can take both of these together if she doubles the dose of Excedrin PM: Doubling the dose would dangerously increase acetaminophen and diphenhydramine intake, raising the risk of liver injury, sedation, and other adverse effects. This is unsafe and not recommended.
Correct Answer is A
Explanation
A. Emollient laxatives: Emollient (stool-softening) laxatives, such as docusate sodium, are considered safe for short-term use in pregnancy. They work by softening the stool and easing passage without stimulating the bowel or causing fluid shifts, making them appropriate for up to two weeks.
B. Stimulant laxatives: Stimulant laxatives, like bisacodyl or senna, directly stimulate intestinal motility and can cause cramping or electrolyte imbalances. They are generally avoided in pregnancy because they may induce uterine contractions or dehydration.
C. Saline laxatives: Saline laxatives, such as magnesium hydroxide or magnesium citrate, draw water into the intestines and can cause fluid and electrolyte disturbances. They are typically not recommended in pregnancy due to potential maternal and fetal complications.
D. None of these categories of laxatives would be safe to use in a pregnant female: This is inaccurate because emollient laxatives have a good safety profile in pregnancy and are commonly recommended for short-term relief of constipation.
