A nurse is performing a physical assessment of a newborn whose mother used cocaine throughout the pregnancy.
Which of the following findings should the nurse expect?

Irritability.

Hypotonicity.

Decreased auditory startle response.

Increased head circumference.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Irritability is a common withdrawal symptom in newborns exposed to cocaine during pregnancy. Cocaine exposure can lead to irritability, restlessness, and difficulty in consoling the newborn.

Choice B rationale:

Hypotonicity, or decreased muscle tone, is not a common finding associated with cocaine exposure in newborns. Cocaine exposure more commonly results in hypertonicity, where the muscles are tense and rigid.

Choice C rationale:

Decreased auditory startle response is not a typical finding associated with cocaine exposure. Newborns exposed to cocaine may have an exaggerated startle response, which is the opposite of the expected finding in this case.

Choice D rationale:

Increased head circumference is not a characteristic finding associated with cocaine exposure. Cocaine exposure is more likely to cause growth restriction, low birth weight, and microcephaly (small head size) in newborns.

Correct Answer is A

Explanation

- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.

- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.

- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.

- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs

A. Telephone number. B. Place of birth. C. Driver license number. D. Room number.

Correct Answer is A

Explanation

Choice A rationale:

The nurse should use the client's telephone number or another unique identifier, such as a medical record number or a unique identification code, to confirm the client's identity before administering medication. Using a telephone number or a unique identifier ensures accurate identification of the client and helps prevent medication errors.

Choice B rationale:

Place of birth is not a suitable identifier for confirming a client's identity. It does not provide specific and accurate information about the individual and may not be unique to the client.

Choice C rationale:

Driver license number is not a suitable identifier for confirming a client's identity. It may not be readily available in the healthcare setting, and not all clients have a driver's license. Using this identifier could lead to identification errors.

Choice D rationale:

Room number is not a suitable identifier for confirming a client's identity. Room numbers are not unique to individual clients and can change based on hospital assignments. Relying on room numbers can lead to confusion and medication errors.
