A nurse is teaching about safe handling of formula to a client who is postpartum and chooses to bottle feed her newborn.
Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:

The nurse should include the statement, "Use a product with DEET on your skin and clothes when you are walking in a wooded area," in the educational program on Lyme disease. DEET is a widely used insect repellent effective against ticks. It is recommended to prevent tick bites in wooded and grassy areas. The rationale behind this choice is to educate the public about practical measures to reduce the risk of Lyme disease. DEET repels ticks, reducing the chances of tick attachment and, consequently, the transmission of Lyme disease.

Choice B rationale:

The statement, "Symptoms of Lyme disease appear 2 days after being bitten by an infected tick," is incorrect. The incubation period for Lyme disease can vary from 3 to 30 days after the tick bite. Symptoms usually appear within 3 to 14 days but can take longer to manifest. Providing inaccurate information can lead to misunderstanding and inadequate preventive measures.

Choice C rationale:

The statement, "Remove embedded ticks by squeezing the body with tweezers," is incorrect. Improper removal of ticks, such as squeezing the body, can lead to the injection of tick fluids into the host, increasing the risk of disease transmission. The correct method for tick removal is to use fine-tipped tweezers to grasp the tick as close to the skin's surface as possible and pull upward with steady, even pressure. This helps ensure the tick is removed entirely and reduces the risk of infection.

Choice D rationale:

The statement, "If bitten by a tick, testing for Lyme disease should occur within 2 weeks," is incorrect. Testing for Lyme disease immediately after a tick bite is not recommended because it takes time for the body to produce antibodies detectable by the tests. Testing too early can yield false-negative results. Healthcare providers may recommend testing if symptoms develop, but waiting for a few weeks after the bite increases the accuracy of the test results.

• A is incorrect because assessing the apical pulse while the newborn is crying can result in an inaccurate measurement due to increased heart rate and respiratory rate.
• B is incorrect because palpating the radial pulse for 30 seconds is not appropriate for a newborn as it can be difficult to locate and count accurately.
• C is incorrect because listening to the apical pulse while palpating the radial pulse is not necessary for a newborn and can be confusing and time-consuming.
• D is correct because auscultating the apical pulse at least 1 min is the best way to assess a newborn's heart rate as it provides an accurate and reliable measurement.
