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.

Answer and Explanation

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) Measure heart chamber pressures to assess for heart failure:
Measuring heart chamber pressures is an important diagnostic tool in assessing heart failure, but it is not the primary goal in the case of a STEMI (ST-Elevation Myocardial Infarction). In STEMI, the primary goal is to identify and treat the blockage in the coronary arteries that is causing the heart attack.

B) Determine cardiac output during the procedure:
Cardiac output is a useful measurement for assessing heart function, but it is not the main focus during the treatment of STEMI. While monitoring cardiac output may be part of the overall care, the urgent priority in STEMI management is to restore blood flow to the affected myocardial tissue as quickly as possible to minimize damage, not to measure cardiac output.

C) Evaluate the extent of the occlusion of the coronary arteries involved:
While evaluating the extent of coronary artery occlusion is part of the process during a cardiac catheterization, the immediate priority for a patient with STEMI is to treat the blockage, not just evaluate it. While the angiogram will reveal the blockage, the treatment goal is to restore perfusion to the affected area of the heart through procedures such as balloon angioplasty or stent placement.

D) Prevent extensive myocardial damage:
This is the correct answer. The main goal of treatment for STEMI is to prevent extensive myocardial damage. In a STEMI, the coronary artery is blocked, depriving the heart muscle of oxygen, which can cause significant damage or death of the myocardial tissue. The most effective way to limit the extent of damage is to restore blood flow as quickly as possible, often through emergent procedures like percutaneous coronary intervention (PCI) or fibrinolytic therapy.

A. single color throughout B. diameter smaller than 2mm. C. has uneven or irregular borders. D. Is symmetrical in shape."

Correct Answer is C

Explanation

A) Single color throughout:
A mole that is a single, consistent color is typically not a concern for melanoma. However, one of the key warning signs of melanoma is a mole that has multiple colors or shades, such as tan, brown, black, or even red or blue. The presence of more than one color in a mole can indicate melanoma, and the client should be advised to seek medical attention if the mole has varied colors.

B) Diameter smaller than 2mm:
A mole that is smaller than 2mm in diameter is typically not a concern for melanoma. Melanomas are often larger than 6mm in diameter, about the size of a pencil eraser, though smaller melanomas can also occur. A mole smaller than 2mm is usually considered benign, but any change in size, shape, or color, regardless of the starting size, should be evaluated.

C) Has uneven or irregular borders:
One of the primary warning signs of melanoma is the presence of irregular or uneven borders on a mole. Normal moles typically have smooth, even borders, while moles with jagged, blurred, or irregular edges are more likely to be melanoma. The client should seek medical attention if they notice any moles with irregular borders, as this could be a sign of malignancy.

D) Is symmetrical in shape:
A mole that is symmetrical (both halves are the same size and shape) is generally not a concern for melanoma. In contrast, asymmetry (when one half of the mole does not match the other half) is a key warning sign for melanoma. A mole that lacks symmetry should be evaluated by a healthcare provider.
