How many liters per minute of oxygen should be administered to the patient with emphysema?
- A. 2 L/min
- B. 10 L/min
- C. 6 L/min
- D. 95 L/min
Correct Answer: C
Rationale: Oxygen therapy for patients with emphysema aims to maintain adequate oxygen levels in the blood while avoiding toxic levels of oxygen. The recommended flow rate for oxygen administration in patients with emphysema is typically 1-3 liters per minute. Increasing the flow rate above this range may lead to oxygen toxicity in these patients. Therefore, a safe and appropriate oxygen flow rate for a patient with emphysema would be around 6 L/min, making option C, 6 L/min, the correct choice from the provided options.

Which of the ff. medications might be ordered to help control symptoms of multiple sclerosis, and possibly induce a remission?
- A. Acyclovir
- B. Thyrotropin
- C. ACTH
- D. Benadryl
Correct Answer: C
Rationale: ACTH (Adrenocorticotropic hormone) might be ordered to help control symptoms of multiple sclerosis and possibly induce a remission. ACTH is sometimes used as a treatment option for multiple sclerosis due to its anti-inflammatory properties. It can help reduce inflammation in the central nervous system and, in some cases, lead to a decrease in symptoms and possibly induce a remission. However, it is important to note that ACTH is not commonly used as a first-line treatment for multiple sclerosis and is usually reserved for cases that are refractory to other medications.
Which of the ff. would the nurse explain to the patient is indicated by a Snellen chart finding 20/80?
- A. The eye can see at 80 feet what the normal eye can see at 20 feet.
- B. The eye can see at 20 feet what the normal eye can see at 80 feet.
- C. The eye can see four times what the normal eye can see.
- D. The eye sees normally.
Correct Answer: A
Rationale: The Snellen chart is a chart used to measure visual acuity. The numbers in a Snellen fraction indicate the distance from which a person with normal eyesight can see the letters on the chart. In the case of 20/80, this means that the person can see at 80 feet what a person with normal eyesight can see at 20 feet. So, option A is correct as it accurately explains what is indicated by a Snellen chart finding of 20/80.
An adult has been diagnosed with some type of anemia. The results of his blood tests showed: decreased WBC, normal RBC, decreased HCT, decreased Hgb. Based on these data, which of the following nursing diagnosis should the nurse prioritize as the most important?
- A. Potential for infection
- B. Self care deficit
- C. Alteration in infection
- D. Fluid volume excess
Correct Answer: A
Rationale: The decreased white blood cell count (WBC) in the blood tests indicates a potential for infection. White blood cells are crucial for fighting off infections in the body. A decrease in WBC count can result in an impaired immune response, making the individual more susceptible to infections. Therefore, the nurse should prioritize the nursing diagnosis of "Potential for infection" to address the heightened risk of infection in the adult with anemia. It is important to monitor for signs and symptoms of infection, provide appropriate hygiene measures, and implement interventions to prevent infections in this individual.
The parents of a newborn plan to have him circumcised. They ask the nurse about pain associated with this procedure. What knowledge should the nurse's response be based on?
- A. Experience pain with circumcision
- B. Do not experience pain with circumcision
- C. Quickly forget about the pain of circumcision
- D. Are too young for anesthesia or analgesia
Correct Answer: B
Rationale: The response should be based on the fact that newborns do not experience pain with circumcision. This is because newborns do not have a fully developed neurological system to perceive pain in the same way that adults do. Studies have shown that the pain response in newborns is limited, and they are able to quickly recover from minor procedures like circumcision without experiencing long-lasting pain. Therefore, the nurse should inform the parents that newborns do not experience pain with circumcision. This is important for providing accurate information and alleviating the concerns of the parents.
A client has been receiving chemotherapy to treat cancer. Which assessment finding suggests that the client has developed stomatitis (inflammation of the mouth)?
- A. White, cottage cheese-like patches on the
- B. Red, open sores on the oral mucosa
- C. Rust-colored sputum
- D. Yellow tooth discoloration
Correct Answer: B
Rationale: Stomatitis is a common side effect of chemotherapy characterized by inflammation and irritation of the mucous membranes in the mouth. This can present as red, painful sores or ulcers on the oral mucosa. The presence of red, open sores in the mouth is indicative of stomatitis and warrants assessment and intervention to manage discomfort and prevent infection in the oral cavity. The other options are not typically associated with stomatitis in the context of chemotherapy.
