During an interview, the patient states he has the sensation that 'everything around him is spinning.' The nurse recognizes that the portion of the ear responsible for this sensation is the:

Correct Answer: D

Rationale: The correct answer is D: Labyrinth. The labyrinth is a structure in the inner ear that contains the vestibular system responsible for balance and spatial orientation. The sensation of spinning or vertigo is related to disturbances in the labyrinth. CN VIII, the vestibulocochlear nerve, carries information from the labyrinth to the brain. The cochlea (A) is responsible for hearing, not balance. The Organ of Corti (C) is a structure within the cochlea involved in hearing, not balance. Therefore, the correct choice is D as it directly relates to the sensation of spinning experienced by the patient.

Correct Answer: C

Rationale: The correct answer is C because tonsils that are 3+/1-4+ with large white spots are indicative of exudative tonsillitis, which commonly occurs in acute bacterial infections like streptococcal pharyngitis. Here's the rationale: 1. Tonsils 3+ indicate significant enlargement, more than the normal size. 2. 1-4+ refers to the extent of the white spots or exudate present on the tonsils. 3. Large white spots suggest a substantial amount of exudate, commonly seen in bacterial infections like streptococcal pharyngitis. Therefore, the presentation of enlarged tonsils with large white spots aligns with an acute bacterial infection. Other choices are incorrect: A: Tonsils are not significantly enlarged nor do they have white spots. B: While there is white debris, it is not extensive as indicated by the 1-4+ scale. D: Pale coloring does not indicate an

Correct Answer: A

Rationale: The correct answer is A: The spinous process of C7. The vertebra prominens is the most prominent vertebra at the base of the neck, which is C7. This is because the spinous process of C7 is longer and more palpable than other cervical vertebrae. Rationales for the incorrect choices: B: Usually nonpalpable in most individuals - This is incorrect as the vertebra prominens (C7) is usually palpable due to its prominent spinous process. C: Opposite the interior border of the scapula - This is incorrect as the vertebra prominens is located at the base of the neck, not opposite the scapula. D: Located next to the manubrium of the sternum - This is incorrect as the vertebra prominens is located higher up in the neck than the manubrium of the sternum.

Correct Answer: B

Rationale: The correct answer is B: When part of the lung is obstructed or collapsed. Unequal chest expansion can occur when there is an obstruction or collapse of a portion of the lung, leading to decreased lung expansion on that side. This can result in one side of the chest moving less during breathing. Other options are incorrect because: A: In an obese patient - obesity may affect chest wall movement but does not directly cause unequal chest expansion. C: When bulging of the intercostal spaces is present - bulging of intercostal spaces may indicate increased work of breathing but does not necessarily lead to unequal chest expansion. D: When accessory muscles are used to augment respiratory effort - while accessory muscles may be used in respiratory distress, they do not directly cause unequal chest expansion.

Correct Answer: D

Rationale: The correct answer is D because the statement accurately describes colostrum, the first milk produced during pregnancy. Colostrum is a thick, yellow fluid that can be expressed from the breasts as early as the fourth month of pregnancy. It is rich in antibodies and nutrients essential for the newborn. A: Incorrect. Breast milk does not immediately appear after delivery; it takes a few days for mature milk to come in. B: Incorrect. Breast milk is rich in fat, not just protein and sugars. Fat is crucial for a baby's growth and development. C: Incorrect. Colostrum is a nutrient-rich fluid that provides essential nutrients to the newborn, even though it may not have the same composition as mature breast milk. In summary, choice D is correct because it accurately describes the early milk production during pregnancy, while the other choices provide inaccurate information about breast milk.
