Nokea
What drug might the nurse administer to achieve both analgesic and antitussive effects?
- A. Acetaminophen.
- B. Ibuprofen.
- C. Aspirin.
- D. Codeine.
Correct Answer: D
Rationale: The correct answer is D: Codeine. Codeine is an opioid analgesic that acts on the central nervous system to relieve pain and suppress coughing. It has both analgesic and antitussive properties, making it the ideal choice for achieving both effects. Acetaminophen (choice A) and ibuprofen (choice B) are analgesics but do not have antitussive effects. Aspirin (choice C) is an analgesic and anti-inflammatory drug but is not commonly used for cough suppression. Therefore, codeine is the most appropriate option for achieving both analgesic and antitussive effects.

A patient who has epilepsy will begin an anticonvulsant medication. The patient asks the nurse how long the medication will be necessary. How will the nurse respond?
- A. You will take the medication as needed for seizure activity.
- B. The medication will be given until you are seizure free.
- C. You will take the medication for 3 to 5 years.
- D. The medication is usually taken for a lifetime.
Correct Answer: D
Rationale: The correct answer is D: The medication is usually taken for a lifetime. The rationale for this is that epilepsy is a chronic condition characterized by recurrent seizures. Anticonvulsant medications are typically prescribed long-term to help control and prevent seizures. Discontinuing the medication can lead to breakthrough seizures and potential risks to the patient's safety and well-being. Choices A and B are incorrect because anticonvulsants are not typically taken on an as-needed basis and the goal is not just to be seizure-free temporarily. Choice C is incorrect as the duration of anticonvulsant therapy may vary depending on the individual's condition and response to treatment, but it is often longer than 3 to 5 years.
Identify a reason a narcotic agent may be prescribed.
- A. Relief of moderate acute pain.
- B. Relief of minor pain.
- C. Analgesia during sleep.
- D. Analgesia during anesthesia.
Correct Answer: A
Rationale: The correct answer is A: Relief of moderate acute pain. Narcotic agents are potent pain relievers typically prescribed for moderate to severe acute pain due to their strong analgesic properties. They work by binding to opioid receptors in the brain and spinal cord, blocking pain signals. Choice B is incorrect as narcotics are usually reserved for more intense pain. Choices C and D are incorrect because narcotics are not typically used for analgesia during sleep or anesthesia, as they can cause respiratory depression and other complications.
A nurse is caring for a neonate born with a congenital heart abnormality. To better help the parents understand the impact of this disorder, the nurse begins by describing the unusual flow of blood through the heart which takes what course?
- A. Deoxygenated blood from the lungs enters the left atrium through the pulmonary artery.
- B. Deoxygenated blood from the lungs enters the right atrium through the pulmonary artery.
- C. Oxygenated blood from the lungs enters the right atrium through the pulmonary veins.
- D. Oxygenated blood from the lungs enters the left atrium through the pulmonary veins.
Correct Answer: D
Rationale: The correct answer is D. In a normal heart, oxygenated blood from the lungs enters the left atrium through the pulmonary veins. This oxygen-rich blood then flows into the left ventricle and is pumped out to the body. In a neonate with a congenital heart abnormality, this pathway may be disrupted, leading to potential complications.
Choice A is incorrect because deoxygenated blood from the body, not the lungs, enters the right atrium through the vena cava. Choice B is incorrect as deoxygenated blood from the lungs enters the right atrium through the superior and inferior vena cava. Choice C is incorrect as oxygenated blood from the lungs enters the left atrium, not the right atrium.
Understanding the normal flow of blood through the heart is crucial for comprehending the impact of congenital heart abnormalities on circulation and oxygenation in neonates.
A 6-year-old was complaining of elbow pain. The nurse will advise the patient to give which pain medication?
- A. Aleve.
- B. Motrin.
- C. Acetaminophen (Tylenol).
- D. Aspirin (Ecotin).
Correct Answer: C
Rationale: The correct answer is C, Acetaminophen (Tylenol). Acetaminophen is the safest pain medication for children due to its low risk of side effects like gastrointestinal irritation or bleeding, which can be more common with Aleve (A), Motrin (B), and Aspirin (D). Aspirin specifically is contraindicated in children due to the risk of Reye's syndrome. Acetaminophen is also preferred because it has antipyretic properties, making it effective for reducing fever in addition to pain relief. Ultimately, Acetaminophen is the best choice for a 6-year-old experiencing elbow pain due to its safety profile and effectiveness in managing pain and fever.
A patient diagnosed with Heart Failure would like the nurse to explain what the diagnosis means. How will the nurse explain heart failure?
- A. The heart muscle cannot pump effectively, causing a backup of blood.
- B. Increased protein leads to reduced oncotic pressure and inability to pull the fluid into the system.
- C. The hydrostatic pressure pushing fluids out of the capillary is lower than the oncotic pressure.
- D. The decrease in venous pressure from the backup of blood increases hydrostatic pressure.
Correct Answer: A
Rationale: The correct answer is A: The heart muscle cannot pump effectively, causing a backup of blood. This is the most accurate explanation of heart failure. In heart failure, the heart is unable to pump blood efficiently, leading to a backup of blood in the circulatory system. This can result in symptoms such as shortness of breath, fatigue, and fluid retention.
Explanation for why the other choices are incorrect:
B: Increased protein leading to reduced oncotic pressure is not a direct cause of heart failure.
C: This choice describes the forces involved in fluid movement, not the primary mechanism of heart failure.
D: Heart failure causes a backup of blood, which in turn increases venous pressure, not the other way around.
In summary, choice A is correct as it directly addresses the primary issue of heart failure, while the other choices focus on different physiological processes not directly related to heart failure.
