Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: The patient's presentation of sudden-onset weakness and sensory loss on one side of the body, along with difficulty speaking and understanding speech that partially resolved within one hour, is consistent with a transient ischemic attack (TIA). TIAs are caused by temporary disruption of blood flow to a part of the brain, leading to transient neurological symptoms. Unlike an ischemic stroke, which results in permanent damage to brain tissue due to prolonged interruption of blood flow, TIAs are transient and resolve within 24 hours. Hemorrhagic strokes and subarachnoid hemorrhages typically present with sudden, severe headaches, and may not improve or resolve quickly as seen in this case.

Correct Answer: C

Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.

Correct Answer: B

Rationale: In quantitative research, randomness plays a crucial role in eliminating bias. Random sampling ensures that every individual or element in the population has an equal chance of being selected for the study. This helps in reducing the possibility of bias creeping into the results due to selective sampling or favoritism towards certain groups. By using random sampling methods, researchers can increase the generalizability of their findings and have a higher level of confidence that the results are unbiased and representative of the entire population. Therefore, randomness is a key mechanism to eliminate bias in quantitative research studies.

Correct Answer: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.

Correct Answer: A

Rationale: The correct way to apply anti-scabies lotion is to cover all skin areas, not just the affected areas or red areas. Scabies is a contagious skin condition caused by mites burrowing into the skin, so applying the lotion to all skin areas helps to eliminate the mites and prevent reinfestation. It is important to follow the instructions provided by the healthcare professional for proper application and treatment of scabies.
