1. Which biomolecule is responsible for the storage and transfer of genetic information?

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

2. 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?

Correct answer: D

Rationale: A low-protein diet should be followed for three months before conception in individuals with PKU who are planning a pregnancy. This diet helps manage PKU by reducing phenylalanine levels, which is crucial for maternal and fetal health. Choices A, B, and C are incorrect. Choice A is not directly related to managing PKU, choice B focuses on a different aspect of care during pregnancy, and choice C is inaccurate as breastfeeding will not prevent a baby from developing PKU.

3. The mother of a drug dependent would never consider referring her son to a drug rehabilitation agency because she fears her son might just become worse while relating with other drug users. The mother’s behavior can be described as:

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Which statement about essential nutrients should the nurse include?

Correct answer: C

Rationale: The correct answer is C because carbohydrates are indeed the primary source of fuel for muscles and the brain. Choice A is incorrect because while certain fats are essential, they do not help decrease triglyceride levels. Choice B is incorrect because animal sources of protein do not contain all 20 essential amino acids. Choice D is incorrect because although high-fiber foods are important for digestion and overall health, they are not a direct source of energy.

5. How many words does a typical 12-month-old infant use?

Correct answer: D

Rationale: A typical 12-month-old infant typically uses very few words, with 'mama' and 'papa' being common early words. At this age, most infants are still in the early stages of language development, and their vocabulary is limited. Choices A, B, and C suggest higher word counts which are not typical for infants at this age.
