1. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?

A. inhibition of the parasympathetic reflex
B. weakness of sphincter muscles of anus
C. loss of tone of the smooth muscles of the colon
D. decreased ability to absorb fluids in the lower intestines

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.

2. What is the function of villi and microvilli in the GI tract?

A. produce bile
B. kill bacteria
C. produce vitamin K
D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

3. When should a newborn transition to whole milk according to dietary teaching for breastfeeding parents?

A. 6 months
B. 8 months
C. 10 months
D. 12 months

Correct answer: D

Rationale: Breast milk or formula should be the primary source of nutrition for infants up to around 1 year of age. The transition to whole cow's milk is recommended at 12 months of age, not earlier. Introducing whole milk before 12 months can lead to digestive issues and nutrient deficiencies. Therefore, choices A, B, and C are incorrect as they suggest transitioning to whole milk before the recommended age of 12 months.

4. A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses?

A. Phosphorus
B. Calcium
C. Chloride
D. Zinc

Correct answer: B

Rationale: Corrected Question: A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses? Correct Answer: Calcium Rationale: Calcium is crucial for nerve transmission, muscle contraction, and blood clotting. It plays a vital role in the proper functioning of the nervous system. Phosphorus is important for bone health and energy metabolism, not nerve impulse transmission. Chloride is an electrolyte important for fluid balance but not directly involved in nerve impulse transmission. Zinc is essential for immune function and wound healing but not specifically required for nerve impulse transmission.

5. Which of the following is not true about Pure Experimental research?

A. There is a control group
B. There is an experimental group
C. Selection of subjects in the control group is randomized
D. There is a careful selection of subjects in the experimental group

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.
