A nurse is preparing to administer digoxin to a 6-month-old infant. Before administering the dose, the nurse measures the apical heart rate.

The nurse should withhold the dose if the infant’s apical heart rate is less than what rate? .

Choice A rationale
The nurse should be concerned about a client with an 18kg (4 lb) weight gain in her first trimester. This is because the expected weight gain for a client in the first trimester is usually around 1.8 kg (4 lb)1. A weight gain of 18 kg in the first trimester significantly exceeds this expectation, which could indicate a potential health issue such as gestational diabetes or multiple pregnancies. It’s important for the nurse to report this finding to the healthcare provider for further evaluation and management.
Choice B rationale
A client with a 68 kg (15 lb) weight gain in her second trimester does not necessarily pose a concern. Weight gain during pregnancy varies among individuals and can be influenced by factors such as the mother’s body mass index (BMI) before pregnancy, the baby’s growth rate, and the mother’s diet and lifestyle. However, it’s always important to monitor weight gain throughout pregnancy to ensure it’s within a healthy range.
Choice C rationale
A client with a 13 kg (25 lb) weight gain in her third trimester does not necessarily pose a concern. Weight gain during the third trimester can be influenced by factors such as the baby’s growth rate, amniotic fluid volume, and the mother’s increased blood volume. However, it’s always important to monitor weight gain throughout pregnancy to ensure it’s within a healthy range.
Choice D rationale
A client with a 3.6 kg (8 lb) weight gain in her first trimester does not necessarily pose a concern. This is within the expected weight gain range for the first trimester. However, it’s always important to monitor weight gain throughout pregnancy to ensure it’s within a healthy range.

Choice A rationale
While an area of warmth can be a symptom of deep vein thrombosis (DVT), it is not the most specific or indicative symptom. DVT is a condition in which blood clots form in veins located deep inside the body, usually in the thigh or lower legs. The most common symptoms include swelling of the foot, ankle, or leg, usually on one side, cramping of the affected leg, severe leg pain, and skin on the affected area that is warmer than the skin on surrounding areas.
However, these symptoms can also be associated with other conditions, making them less specific for DVT.
Choice B rationale
Nausea is not typically a symptom of deep vein thrombosis (DVT). The most common symptoms of DVT include swelling of the foot, ankle, or leg, usually on one side, cramping of the affected leg, severe leg pain, and skin on the affected area that is warmer than the skin on surrounding areas.
Choice C rationale
A cool-to-touch extremity is not typically a symptom of deep vein thrombosis (DVT). In fact, the skin over the affected area is often warmer than the skin on surrounding areas. Therefore, a cool-to-touch extremity would not typically be expected in a client with suspected DVT.
Choice D rationale
Calf tenderness when massaged is a common clinical finding in clients with deep vein thrombosis (DVT)2. DVT often causes pain and swelling in the affected leg, and this pain can be particularly noticeable or worsen when the calf is massaged or the client is standing or walking. Therefore, calf tenderness when massaged would be a clinical finding that a nurse should anticipate in a client being admitted with a suspected DVT.
