Correct Answer: B

Rationale: The correct answer is B: Canned soup. Canned soup is commonly high in sodium content, which is not suitable for a patient on a low-sodium diet. Fresh fruit, whole grain bread, and grilled chicken typically have lower sodium levels and can be included in a low-sodium diet. Therefore, the patient should avoid canned soup to adhere to the requirements of a low-sodium diet.

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.

Correct Answer: A

Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.

Correct Answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.

Correct Answer: C

Rationale: The correct symptoms associated with cancer of the colon are blood in the stools, anemia, and 'pencil-shaped' stools. These symptoms are classic indicators of colorectal cancer. Choices A, B, and D do not typically present in colorectal cancer. Constipation, ascites, and mucus in the stool are more commonly associated with other gastrointestinal conditions. Diarrhea, heartburn, and eructation are not typical symptoms of colon cancer. Anorexia, hematemesis, and increased peristalsis are more indicative of other gastrointestinal issues and not specific to colon cancer.
