If exhibited by a pregnant woman, what represents a positive sign of pregnancy?

Morning sickness.

Quickening.

Positive pregnancy test.

Fetal heartbeat auscultated with Doppler/fetoscope.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Morning sickness, which refers to nausea and vomiting during pregnancy, is a common symptom but not a definitive sign of pregnancy. It can also be caused by various other factors such as food poisoning or gastrointestinal issues. Therefore, it is not a positive sign of pregnancy.

Choice B rationale:

Quickening, which refers to the first fetal movements felt by the mother, is a subjective sign of pregnancy. It is not a definitive indication of pregnancy as it can be mistaken for other abdominal sensations. Quickening usually occurs between 18 to 22 weeks of gestation, making it a later sign and not an early positive sign of pregnancy.

Choice C rationale:

A positive pregnancy test, specifically a blood or urine test detecting human chorionic gonadotropin (hCG), is a reliable indicator of pregnancy. However, it is a biochemical sign and not a physical sign. It does not directly confirm the presence of the fetus or its well-being, making it less specific than auscultating the fetal heartbeat.

Choice D rationale:

Fetal heartbeat auscultated with Doppler/fetoscope is a positive sign of pregnancy. The healthcare provider can hear the fetal heartbeat using a Doppler ultrasound device or fetoscope, confirming the presence of a viable pregnancy. This sign is considered positive because it directly indicates the presence of a developing fetus, providing reassurance about the pregnancy status. Fetal heartbeat can usually be detected around 10 to 12 weeks of gestation.

Correct Answer is C

Explanation

Choice A rationale:
Cough. While a cough can be a side effect of inhaled steroids, it is not a significant concern compared to other potential risks. Long-term use of inhaled steroids can lead to slowed growth in children, making choice C the correct answer.
Choice B rationale:
Osteoporosis. Osteoporosis is a potential side effect of long-term use of inhaled steroids. These medications can affect bone density and increase the risk of osteoporosis, especially in individuals who are already at risk due to other factors such as age, gender, or family history.
Choice C rationale:
Slowed growth. Long-term use of inhaled steroids can lead to slowed growth in children. It's important for healthcare providers to monitor the growth of children with asthma who are taking these medications regularly. If slowed growth is observed, healthcare providers might consider adjusting the treatment plan.
Choice D rationale:
Cushing's syndrome. Cushing's syndrome is a rare but serious side effect of long-term steroid use. It is characterized by a collection of signs and symptoms caused by prolonged exposure to high levels of cortisol (a steroid hormone). While it's a potential risk, slowed growth is a more common concern in children taking long-term inhaled steroids.

A. "Surfactant improves the ability of your baby's lungs to exchange oxygen and carbon dioxide.". B. "The drug keeps your baby from requiring too much sedation.". C. "Surfactant is used to reduce episodes of periodic apnea.". D. "Your baby needs this medication to fight a possible respiratory tract infection.".

Correct Answer is A

Explanation

Choice A rationale:

The correct answer. Surfactant is a substance that decreases surface tension in the alveoli of the lungs, preventing them from collapsing and sticking together. By improving the ability of the baby's lungs to exchange oxygen and carbon dioxide, surfactant therapy helps the infant breathe more effectively.

Choice B rationale:

Surfactant therapy is not related to sedation. Its primary function is to assist with lung function, not sedation.

Choice C rationale:

Surfactant therapy does not specifically address apnea. Its main purpose is to enhance the respiratory function of premature infants.

Choice D rationale:

Surfactant therapy is not used to fight respiratory tract infections. It is a treatment focused on improving the respiratory distress syndrome in premature infants.
