A nurse is reinforcing teaching with an adolescent client who uses inhalers for the treatment of asthma. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason:

Hypothermia. Hypothermia refers to a condition where the body temperature drops significantly below the normal range. However, in cases of acute opioid toxicity, the opposite effect is usually observed. Opioids can cause respiratory depression, leading to a decrease in the body's ability to regulate temperature, resulting in hyperthermia, not hypothermia.

Choice B reason:

Hypertension. Acute opioid toxicity typically causes respiratory depression, which can lead to a decrease in blood pressure rather than hypertension. Opioids are central nervous system depressants that slow down the body's vital functions, including heart rate and blood pressure.

Choice C reason:

Diaphoresis. Diaphoresis is the medical term for excessive sweating. While it may occur in some cases of opioid toxicity due to the body's response to stress or increased sympathetic activity, it is not a specific and consistent finding. It is not as characteristic as other symptoms associated with opioid toxicity.

Choice D reason:

Mydriasis. Mydriasis refers to the dilation of the pupils. This is a hallmark sign of opioid toxicity. Opioids can affect the autonomic nervous system, leading to pupillary constriction (miosis) in most cases. However, when opioid toxicity is severe or acute, the pupils may dilate, resulting in mydriasis.

Choice A reason:

Breast changes are considered a presumptive sign of pregnancy. This means they are subjective indications reported by the woman and may not be definitive evidence of pregnancy. During pregnancy, the woman's breasts may undergo various changes such as tenderness, enlargement, and darkening of the areolas. These changes are primarily due to hormonal fluctuations and increased blood flow to the breast tissue.

Choice B reason:

Ballottement is not a presumptive sign of pregnancy. Ballottement is a clinical maneuver performed by a healthcare provider to assess the mobility of the fetus in the amniotic fluid. It involves tapping on the cervix and feeling for a rebound from the floating fetus. While it is an indication of pregnancy, it is not considered a presumptive sign as it requires a trained professional to detect.

Choice C reason:

Urinary frequency is a presumptive sign of pregnancy. During pregnancy, the growing uterus can put pressure on the bladder, leading to increased urinary frequency. However, urinary frequency can also be caused by other factors such as urinary tract infections, so it is not a definitive sign of pregnancy.

Choice D reason:

Nausea, specifically morning sickness, is a presumptive sign of pregnancy. Many pregnant women experience nausea and vomiting, especially during the first trimester, due to hormonal changes. However, nausea can also be caused by various other conditions, making it a presumptive rather than a confirmatory sign of pregnancy.

Choice E:

A positive pregnancy test is a probable sign of pregnancy rather than a presumptive sign. Pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy. A positive test provides strong evidence of pregnancy, but it is not considered a presumptive sign as it is an objective finding rather than a subjective symptom reported by the woman.
