A nurse is providing anticipatory guidance to a client who has phenylketonuria (PKU) and is planning a pregnancy. Which of the following information should the nurse include in the discussion?
"Diet sodas should not be consumed more than two or three times per week."
"A low-protein diet should be followed for 3 months prior to conception."
"Serum bilirubin should be monitored one to two times per month during pregnancy."
"Breastfeeding will prevent your baby from developing PKU."
The Correct Answer is B
Phenylketonuria (PKU) is an inherited metabolic disorder in which the body cannot properly process an amino acid called phenylalanine. If left untreated, phenylalanine can build up to harmful levels in the body, leading to intellectual disability and other health problems. Managing PKU involves following a strict low-phenylalanine diet.
When discussing anticipatory guidance for a client with PKU who is planning a pregnancy, it is important to focus on monitoring the maternal phenylalanine levels during pregnancy. Serum bilirubin is not directly related to PKU management and would not require specific monitoring in this context.
Regarding the other options:
"Diet sodas should not be consumed more than two or three times per week": While it is generally advisable to limit the consumption of diet sodas due to their artificial sweeteners, this statement does not directly relate to PKU management or pregnancy planning.
"A low-protein diet should be followed for 3 months prior to conception": A low-protein diet is a fundamental aspect of managing PKU. However, the timeline mentioned (3 months prior to conception) is not supported by current guidelines. PKU management should be ongoing and tailored to the individual's needs, with dietary adjustments made as necessary throughout pregnancy.
"Breastfeeding will prevent your baby from developing PKU": This statement is incorrect. Breast milk naturally contains phenylalanine, which could be harmful to an infant with PKU. Infants with PKU must receive a specialized formula that is low in phenylalanine from birth. Breastfeeding is not recommended for infants with PKU unless specifically guided by a healthcare professional.

Correct Answer is C
Explanation
Iron-deficiency anemia is characterized by a deficiency of iron, which is necessary for the production of hemoglobin in red blood cells. Ferritin is a protein that stores iron in the body, and a low ferritin level is an indicator of depleted iron stores.
Ferritin: The normal range for ferritin varies depending on the laboratory, but typically it is around 12 to 300 ng/mL for females and 12 to 500 ng/mL for males. A client with a ferritin level of 8 ng/mL has a significantly low level, suggesting iron-deficiency anemia due to depleted iron stores.
Hematocrit: The normal range for hematocrit is around 36% to 46% for females and 38% to 50% for males. A client with a hematocrit of 42% falls within the normal range and does not suggest iron-deficiency anemia.
Hemoglobin: The normal range for hemoglobin is approximately 12 to 16 g/dL for females and
13.5 to 17.5 g/dL for males. A client with a hemoglobin level of 15 g/dL is within the normal range and does not indicate iron-deficiency anemia.
RBC count: The normal range for red blood cell (RBC) count is roughly 4.2 to 5.4 million/mm3 for females and 4.7 to 6.1 million/mm3 for males. A client with an RBC count of 5.2 million/mm3 falls within the normal range and does not indicate iron-deficiency anemia.
Correct Answer is C
Explanation
Muscle weakness is a finding that indicates the client is experiencing water intoxication. Muscle weakness is a symptom of water intoxication because the excessive intake of water dilutes the sodium levels in the blood, causing hyponatremia. Sodium is an electrolyte that helps maintain the balance of fluids in and around cells and also regulates muscle contraction. When sodium levels are too low, the cells swell and the muscles lose their ability to function properly.
Weak pulses are not a specific finding for water intoxication, as they can be caused by other factors such as decreased blood volume or inadequate cardiac output.
Hypernatremia is the opposite of hyponatremia, meaning high sodium levels in the blood. This can occur due to dehydration, excessive salt intake, or certain medical conditions, but not water intoxication.
Exaggerated reflexes are not typically associated with water intoxication. They may be seen in conditions such as hyperreflexia or certain neurological disorders.
