When should the nurse recommend a pregnant client to contact her healthcare provider?

Recommending that a pregnant client contact her healthcare provider in the case of sudden weight gain is appropriate because it can indicate potential complications. Sudden weight gain may suggest issues such as preeclampsia, gestational diabetes, or other medical conditions that require monitoring and intervention. This weight gain is often considered abnormal, especially if it occurs rapidly over a short period, and it is important for the healthcare provider to evaluate the situation to ensure the health of both the mother and the fetus.

In contrast, morning sickness is a common experience during pregnancy and generally does not warrant immediate medical attention unless it becomes severe. Increased fatigue can also be a normal part of pregnancy, particularly in the first and third trimesters, and is not typically a red flag for serious complications. Light cramping can be normal as the uterus expands, especially in the early stages of pregnancy. However, if cramping is severe or accompanied by other concerning symptoms, then contacting a healthcare provider would be advisable. Thus, sudden weight gain stands out as a more serious concern that requires prompt evaluation by a healthcare professional.
