A nurse is performing a heel stick blood glucose test on a newborn who is preterm.

The nurse should apply a heel warmer to the newborn’s foot before obtaining the blood sample for which of the following reasons?

To prevent infection

To increase blood flow

To reduce pain

To prevent bruising

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. To increase blood flow. A heel warmer is applied to the newborn’s foot before obtaining the blood sample to increase the blood flow to the area and make it easier to collect the sample. A heel warmer can also reduce pain and bruising by dilating the blood vessels and reducing the need for multiple punctures.

Choice A is wrong because a heel warmer does not prevent infection. Infection prevention requires proper cleaning of the puncture site and disposal of the lancet.

Choice C is wrong because a heel warmer does not reduce pain by itself. Pain reduction requires other measures such as cuddling, feeding, and distraction.

Choice D is wrong because a heel warmer does not prevent bruising. Bruising prevention requires applying pressure to the puncture site after collecting the sample.

Normal ranges for blood glucose levels in newborns vary depending on the method of measurement, but generally they are between 2.6 and 6.0 mmol/L.

Correct Answer is A

Explanation

Decreased hCG levels are abnormal regarding hCG levels in pregnancy.hCG is a hormone that plays an important role in pregnancy, and levels can vary widely at this time and between individuals.However, during early pregnancy, hCG levels typically double every two to three days.Low or declining hCG levels can signal a problem with the pregnancy, such as an impending miscarriage or ectopic pregnancy.

Choice B is wrong because unchanged hCG levels are also abnormal regarding hCG levels in pregnancy.

As mentioned above, hCG levels should increase rapidly during the first few weeks of pregnancy.

Choice C is wrong because increased hCG levels are normal regarding hCG levels in pregnancy.Levels of hCG can vary widely from one pregnant woman to another, but they generally peak at around 8 to 14 weeks after conception.

Choice D is wrong because increased prolactin levels are not related to hCG levels in pregnancy.

Prolactin is another hormone that stimulates milk production in the breasts.

Prolactin levels rise during pregnancy and breastfeeding, but they do not affect hCG levels.

Correct Answer is B

Explanation

nswer: b. Encouraging the client to use the call bell for assistance. Explanation: Encouraging the client to use the call bell for assistance is the most important intervention for fall prevention. It promotes the client's involvement in their own safety and ensures that help is readily available when needed.

Incorrect choices: a. Placing a sign on the client's room door indicating fall risk is a helpful visual reminder, but it does not actively prevent falls. c. Providing a nonskid mat on the floor beside the client's bed can reduce the risk of slipping but does not address other factors that contribute to falls. d. Ensuring the client has adequate lighting in the room is important for preventing falls, but it is not the most critical intervention. The client's ability to seek assistance when needed is more crucial.
