Which of the following statements by the client indicates an understanding of the teaching?
A. "I can keep a can of concentrated formula in the refrigerator for 3 days after I open it.”
Keeping a can of concentrated formula in the refrigerator for 3 days after opening it is not safe. Once a can of formula is opened, it should be used within 24 hours and stored in the refrigerator. After 24 hours, any leftover formula should be discarded to prevent the risk of bacterial contamination.
B. "I can dilute the ready-to-feed formula with water when my baby wants more than 4 ounces at a feeding.”
Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.
C. "I should boil tap water for 2 minutes and cool it before I mix it with the powdered formula.”
Boiling tap water for 2 minutes and cooling it before mixing it with powdered formula is the correct method for safe formula preparation. Boiling the water kills harmful bacteria and ensures the formula is safe for the baby to consume. It is essential to cool the boiled water before mixing it with powdered formula to reach an appropriate feeding temperature.
D. "I will be sure that all of my bottles contain BPA.”
Ensuring that all bottles contain BPA (bisphenol A) is not a relevant consideration for formula preparation. BPA is a chemical that was previously used in some plastics, including baby bottles, but has been banned in baby bottles and sippy cups in several countries due to its potential health risks. Most modern baby bottles are BPA-free, and this statement does not address the safe handling and preparation of formula for the baby.

Choice B rationale:
Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.
Choice C rationale:

Similar Questions
A nurse is assessing a client who is at 37 weeks of gestation and reports sudden, severe abdominal pain with moderate vaginal bleeding and persistent uterine contractions.
The client's blood pressure is 88/50 mm Hg, and her abdomen is rigid.
The nurse should identify these findings as indicating which of the following complications?
A. Uterine rupture.
Uterine rupture typically presents with intense, constant abdominal pain and signs of shock. However, the absence of visible bleeding in the abdominal cavity makes this choice less likely in this case.
B. Placental abruption.
Placental abruption involves the premature separation of the placenta from the uterine wall before delivery. The sudden, severe abdominal pain, moderate vaginal bleeding, persistent uterine contractions, and signs of hypovolemic shock (low blood pressure, rigid abdomen) are indicative of placental abruption. This condition requires immediate medical intervention due to the risk of fetal and maternal compromise.
C. Placenta previa.
Placenta previa occurs when the placenta partially or completely covers the cervical opening. It typically presents with painless, bright red vaginal bleeding. The severe abdominal pain described in the scenario is inconsistent with placenta previa.
D. Amniotic fluid embolus.
Amniotic fluid embolus is a rare and life-threatening condition in which amniotic fluid enters the maternal bloodstream, causing an allergic reaction. It can lead to sudden cardiovascular collapse. Although it can cause respiratory distress and hypotension, it does not usually present with severe abdominal pain or uterine contractions.

A nurse is reviewing the results of laboratory screenings for a 9-month-old infant.
Which of the following results should the nurse report to the provider?
A. Lead 18 mcg/dL.
A blood lead level of 18 mcg/dL in a 9-month-old infant is elevated. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 mcg/dL or higher in children to be concerning. Lead exposure can lead to developmental delays and cognitive impairments. Therefore, this result needs to be reported to the healthcare provider promptly.
B. Hemoglobin 12 g/dL.
Hemoglobin level of 12 g/dL is within the normal range for a 9-month-old infant (11-15 g/dL) There is no need to report this result to the provider.
C. Iron 74 mcg/dL.
Iron level of 74 mcg/dL is within the normal range for a 9-month-old infant (50-120 mcg/dL) There is no need to report this result to the provider.
D. Hematocrit 35%.
Hematocrit level of 35% is within the normal range for a 9-month-old infant (29-41%) There is no need to report this result to the provider.

A nurse is creating an incident report due to an accidental omission of a client's dressing change during the previous shift.
Which of the following statements should the nurse document on the incident report form?
A. "Unable to complete a prescribed dressing change. However, dressing did not appear to be soiled.”
This statement implies that the nurse attempted the dressing change but was unsuccessful. However, the information about the dressing not being soiled is irrelevant to the incident report. The key issue is the omission of the prescribed procedure.
B. "A nurse accidentally omitted a prescribed dressing change.
This statement acknowledges the omission but lacks specificity. It does not state the nature of the omission or the potential consequences, making it less informative for future prevention strategies.
C. "Prescribed dressing change was accidentally omitted during the previous shift.”
This statement clearly and concisely states the situation, indicating that the prescribed dressing change was omitted. It provides essential information for understanding what happened, allowing for appropriate investigation and preventive measures.
D. "Incident report completed.
This statement confirms the completion of the incident report but does not provide details about the incident itself. Without specific information about the omission, this statement is insufficient for understanding the nature of the error and implementing preventive actions.
