When assessing a patient's lungs, what should the nurse recall about the left lung?
Is shorter than the right lung because of the underlying stomach.
Primarily consists of an upper lobe on the posterior chest.
Is divided by the horizontal fissure.
Consists of two lobes.
The Correct Answer is D
A. Is shorter than the right lung because of the underlying stomach: The right lung is actually shorter than the left lung due to the position of the liver beneath it, which pushes the right diaphragm higher. The left lung is longer but narrower due to the space occupied by the heart.
B. Primarily consists of an upper lobe on the posterior chest: The left lung has both upper and lower lobes visible on the posterior chest. The lower lobe is larger and occupies most of the posterior lung field, while the upper lobe is primarily seen anteriorly and laterally.
C. Is divided by the horizontal fissure: The horizontal fissure is found in the right lung, separating the upper and middle lobes. The left lung has only one fissure, the oblique fissure, which separates its two lobes.
D. Consists of two lobes: The left lung is divided into an upper and lower lobe by the oblique fissure. Unlike the right lung, which has three lobes, the left lung has only two due to the space occupied by the heart, forming the cardiac notch.

Correct Answer is A
Explanation
A. Thyroid: The thyroid gland produces thyroxine (T4) and triiodothyronine (T3), which are essential hormones that regulate metabolism, growth, and development. An elevated T4 level typically indicates hyperthyroidism or other thyroid disorders, making it necessary to assess the function and health of the thyroid gland.
B. Parathyroid: The parathyroid glands regulate calcium levels in the blood through the secretion of parathyroid hormone (PTH). They do not produce T4 or directly influence thyroid hormone levels, so assessing the parathyroid glands would not be relevant in the context of elevated T4.
C. Adrenal: The adrenal glands produce hormones such as cortisol, aldosterone, and adrenaline. While adrenal function can impact overall hormonal balance in the body, they are not directly involved in the production of thyroxine (T4), making them unrelated to the assessment for elevated T4 levels.
D. Parotid: The parotid glands are major salivary glands that secrete saliva. They do not play a role in thyroid hormone production or regulation, so assessing the parotid glands would not be appropriate when investigating elevated T4 levels.
Correct Answer is C
Explanation
A. Behind with the nurse's hands placed firmly around his neck: This approach may be perceived as threatening or invasive, potentially increasing the patient's apprehension and discomfort. It is important to maintain a respectful and gentle approach, especially when working with a patient who may already feel uneasy.
B. Behind with hands placed on throat: Similar to option A, examining from behind and placing hands on the throat may cause anxiety and discomfort for the patient, particularly if they are not familiar with the procedure. This method does not provide a clear line of sight or reassurance for the patient.
C. The front with the nurse's thumbs placed on either side of his trachea and his head tilted forward: This technique is the most appropriate approach for examining the thyroid gland. Positioning the patient in front allows for better communication and visibility. Placing the thumbs on either side of the trachea is a standard method for palpating the thyroid, and having the patient tilt their head forward can help relax the neck muscles, making the examination more comfortable. Additionally, this approach allows the nurse to explain the procedure more easily, even with language barriers.
D. Have the patient perform the exam: While patient involvement in their care can be empowering, asking the patient to perform the exam may not be appropriate for a thyroid examination, as the nurse must assess the gland's size, consistency, and any potential nodules. This approach may also lead to further anxiety for the patient, who may not know how to perform the exam correctly.
