The neurologic assessment of a patient indicated impaired function of the glossopharyngeal nerve (CN 10) and the vagus nerve (C.N X). Based on these findings, the nurse plans to;
insert an oral airway and suction as needed.
withhold oral fluids and food.
apply artificial pears to protect the cornea.
speak clearly while facing the patient.
The Correct Answer is B
A) Insert an oral airway and suction as needed:
This is generally not the first intervention for impaired glossopharyngeal (CN IX) and vagus nerve (CN X) function. The glossopharyngeal and vagus nerves play a critical role in swallowing, gag reflex, and the ability to protect the airway. While an airway might be necessary in cases of severe dysfunction, withholding food and fluids is a more immediate and specific concern when these cranial nerves are impaired, as it prevents aspiration risk.
B) Withhold oral fluids and food:
The glossopharyngeal nerve (CN IX) is involved in taste and swallowing, and the vagus nerve (CN X) is crucial for the motor control of the pharynx and larynx, which are involved in swallowing and protecting the airway. Dysfunction of these nerves can lead to difficulty swallowing (dysphagia), increased risk for aspiration, and the inability to protect the airway effectively. Withholding oral fluids and food helps prevent aspiration, a major risk when these nerves are impaired, until further assessment and management can be done.
C) Apply artificial tears to protect the cornea:
While it is important to protect the cornea in patients with cranial nerve dysfunction (specifically the facial nerve, CN VII), this does not directly relate to the glossopharyngeal (CN IX) and vagus (CN X) nerves. The glossopharyngeal and vagus nerves affect swallowing and airway protection, not eye lubrication. Applying artificial tears would not address the risk associated with impaired swallowing or airway protection.
D) Speak clearly while facing the patient:
Although speaking clearly and facing the patient might be helpful for communication, especially if the patient has difficulty with speech due to nerve impairment, it does not address the immediate and more critical concern of impaired swallowing and airway protection associated with dysfunction of the glossopharyngeal and vagus nerves. The primary concern is ensuring the patient is not at risk for aspiration while eating or drinking.

Correct Answer is D
Explanation
A) Packed Red Blood Cells (PRBCs):
Packed Red Blood Cells are typically transfused when there is anemia or significant blood loss leading to low hemoglobin levels. In the case of warfarin overdose or elevated PT/INR, the problem is related to coagulation and not red blood cell count.
B) Platelets:
Platelets are typically transfused when there is thrombocytopenia or a need to address platelet dysfunction (e.g., in patients with bleeding due to low platelet counts). However, the elevated PT and INR in this case are related to the coagulation cascade being inhibited by warfarin, not platelet deficiency.
C) Cryoprecipitate:
Cryoprecipitate is primarily used to replace clotting factors such as fibrinogen, factor VIII, and von Willebrand factor. It is typically transfused in patients with hemophilia or bleeding disorders related to low fibrinogen levels. However, in this case, the issue is related to warfarin-induced inhibition of clotting factors (specifically the vitamin K-dependent factors: II, VII, IX, and X), not a deficiency in fibrinogen or specific clotting factors addressed by cryoprecipitate.
D) Fresh Frozen Plasma (FFP):
Fresh Frozen Plasma (FFP) is the most appropriate choice for this patient. FFP contains all the coagulation factors, including the vitamin K-dependent factors that warfarin inhibits. When a patient on warfarin presents with elevated PT and INR (which indicates impaired clotting ability), FFP is used to replace the clotting factors and help reverse the effects of warfarin.
Correct Answer is A
Explanation
A) Unstable:
Unstable angina is the type of angina most closely related to an impending myocardial infarction (MI). It is characterized by unpredictable chest pain that occurs at rest or with minimal exertion, or that increases in severity or frequency. Unstable angina represents a medical emergency and can progress to an MI if not promptly treated. It occurs when there is increased myocardial oxygen demand and a partially occluded coronary artery, often due to a ruptured atherosclerotic plaque.
B) Variant (Prinzmetal's) angina:
Variant angina, also known as Prinzmetal's angina, is caused by a spasm of the coronary artery, which temporarily narrows or obstructs blood flow. Although it can be severe and may occur at rest, it is typically transient and is not directly related to the development of an MI. Variant angina usually responds to medications such as nitrates or calcium channel blockers, and while it can be dangerous, it is not the most likely type of angina associated with a myocardial infarction.
C) Chronic stable angina:
Chronic stable angina occurs with predictable patterns, typically with exertion or stress, and resolves with rest or nitroglycerin. It does not usually indicate an impending MI, as it is a chronic condition caused by atherosclerosis that limits the heart's blood supply under stress. While chronic stable angina increases the risk of MI over time, it is not directly associated with an imminent heart attack.
D) Nocturnal angina:
Nocturnal angina refers to chest pain that occurs during the night or early morning hours, often during sleep. It may be associated with sleep apnea, GERD, or increased sympathetic tone during sleep. This type of angina is less commonly linked to an impending MI compared to unstable angina, although it should still be evaluated for any underlying cardiovascular issues.
