Foundations and Adult Health Nursing Study Guide Answers

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.

Correct Answer: C

Rationale: Providing oral rehydration with electrolyte solutions is the appropriate action for managing a conscious patient with suspected heat cramps. Heat cramps are muscle pains or spasms that often occur during intense exercise in hot environments when a person sweats excessively, losing both fluids and electrolytes. Replenishing lost fluids and electrolytes through oral rehydration helps address the underlying cause of the cramps and provides relief to the patient. Massaging the affected muscles vigorously can potentially worsen the condition, applying cold packs is not usually recommended for heat-related conditions, and encouraging the patient to continue strenuous activity can lead to further complications.

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: B

Rationale: The constellation of severe lower abdominal pain, fever, and vaginal discharge in a pregnant woman raises suspicion for pelvic inflammatory disease (PID). Cervical motion tenderness and adnexal tenderness are classic physical exam findings for PID. The presence of bilateral adnexal masses further supports the diagnosis, as PID can lead to the formation of tubo-ovarian abscesses. Ectopic pregnancy may present with similar symptoms but is less likely in this case as bilateral adnexal masses suggest a more diffuse inflammatory process. Placenta previa would typically present with painless vaginal bleeding in the third trimester, which is not consistent with the symptoms described. Ovarian torsion would present with sudden severe unilateral lower abdominal pain and is less likely to involve both ovaries simultaneously.

Correct Answer: A

Rationale: The presentation of chest pain, dyspnea, hypotension, right ventricular dilation, and hypokinesis on echocardiogram is highly suggestive of a pulmonary embolism. In pulmonary embolism, a blood clot obstructs the pulmonary artery or one of its branches, leading to increased pressure in the right ventricle, which can cause right ventricular dilation and dysfunction. This results in the classic signs of right heart strain on echocardiogram. The patient may also present with symptoms of acute right heart failure, such as chest pain, dyspnea, and signs of hypotension. It is crucial to consider pulmonary embolism as a potential cause of these symptoms, given the high morbidity and mortality associated with this condition.
