Which of the following structures is responsible for propelling food from the oral cavity to the stomach through coordinated muscular contractions?
- A. Tongue
- B. Pharynx
- C. Esophagus
- D. Epiglottis
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.

A patient with asthma experiences nocturnal cough, wheezing, and chest tightness several times per week. Which of the following medications is most appropriate for long-term control of asthma symptoms and prevention of exacerbations?
- A. Fluticasone/salmeterol (Advair)
- B. Albuterol (salbutamol)
- C. Ipratropium bromide (Atrovent)
- D. Prednisone
Correct Answer: A
Rationale: Fluticasone/salmeterol (Advair) is a combination medication consisting of an inhaled corticosteroid (fluticasone) and a long-acting beta-agonist (salmeterol). This combination medication is recommended for long-term control of asthma symptoms and for the prevention of exacerbations. Fluticasone reduces airway inflammation, while salmeterol helps to relax the muscles of the airways, improving breathing. Using this combination medication regularly can help manage asthma symptoms and reduce the risk of asthma attacks. It is not appropriate to use short-acting beta-agonists like albuterol (salbutamol) on a long-term basis for asthma control. Ipratropium bromide (Atrovent) is an anticholinergic bronchodilator that is more commonly used for chronic obstructive pulmonary disease (COPD
Qualitative researchers should choose their participants who can best meet the objectives of the study, who of the following best qualifies?
- A. Cooperative persons in the community
- B. Those readily available thus convenient for the researcher.
- C. Able to articulate and reflect on the phenomenon that they experienced.
- D. Persons referred by friends.
Correct Answer: C
Rationale: When selecting participants for a qualitative research study, it is important to choose individuals who are able to articulate and reflect on the phenomenon being studied. This is crucial for gathering in-depth and rich data that can provide valuable insights for the study. Participants who can express their experiences, thoughts, and feelings clearly will allow the researcher to delve deeper into the research objectives and gain a more comprehensive understanding of the phenomenon under investigation. Selecting individuals with the ability to articulate and reflect ensures that the data collected will be meaningful and contribute significantly to the research findings. It is essential for qualitative researchers to prioritize such participants who can best meet the objectives of the study by offering detailed and insightful perspectives.
A postpartum client presents with calf pain, swelling, and warmth. Which nursing action is most appropriate?
- A. Applying a warm compress to the affected calf
- B. Encouraging ambulation to promote circulation
- C. Notifying the healthcare provider immediately
- D. Administering a nonsteroidal anti-inflammatory drug (NSAID) for pain relief
Correct Answer: C
Rationale: The most appropriate nursing action in this scenario is to notify the healthcare provider immediately. The client's presentation of calf pain, swelling, and warmth could be indicative of a deep vein thrombosis (DVT), which is a serious condition that requires prompt evaluation and intervention by the healthcare provider. DVT is a blood clot that forms in a deep vein, often in the leg, and if left untreated, it can lead to life-threatening complications such as pulmonary embolism. Therefore, timely communication with the healthcare provider is critical to ensure that the client receives the appropriate diagnostic testing and treatment to address the potential DVT. Applying warm compresses, encouraging ambulation, or administering NSAIDs would not be the first-line interventions for a suspected DVT and may even worsen the condition.
Mrs. Carpio has an order of Thiazide diuretics for her edema. The following is the entry that you expect to be written in her progress report EXCEPT ______.
- A. Serum electrolyte monitored everyday
- B. Intake and output done every shift
- C. Weight taken before drug is administered
- D. Drug is administered at 8o'clock in the evening
Correct Answer: D
Rationale: The entry you expect to be written in Mrs. Carpio's progress report should include details related to monitoring her response to the Thiazide diuretics and ensuring her safety. Options A, B, and C all focus on these aspects by monitoring serum electrolytes, intake and output, and weight before drug administration, which are important considerations when a patient is on Thiazide diuretics. However, specifying the time of drug administration (8 o'clock in the evening) is not necessary in the progress report entry. The focus should be on the patient's response to the medication and the associated monitoring parameters. Time of administration is more relevant for nursing care plans or medication schedules.
A patient with a history of heart failure is prescribed carvedilol. Which parameter should the nurse monitor closely during carvedilol therapy?
- A. Blood glucose levels
- B. Serum potassium levels
- C. Blood pressure
- D. Liver function tests Medical Surgical Nursing
Correct Answer: C
Rationale: Carvedilol is a beta-blocker primarily used to manage heart failure and hypertension. Monitoring blood pressure closely during carvedilol therapy is crucial because it helps assess the drug's effectiveness in managing heart failure and controlling hypertension. Carvedilol works by blocking certain receptors in the heart and blood vessels, which can lower blood pressure. Monitoring blood pressure fluctuations allows healthcare providers to adjust the dosage accordingly to achieve optimal results and prevent potential complications in patients with heart failure. While monitoring blood glucose levels, serum potassium levels, and liver function tests are essential in managing other conditions or medications, the priority in a patient being prescribed carvedilol for heart failure is to monitor blood pressure levels.
