A nurse is assessing a client for a positive Chvostek's sign following a thyroidectomy. Which of the following areas on the client's head should the nurse tap to assess the client for tetany?
The Correct Answer is B
To assess a client for a positive Chvostek’s sign, the nurse should tap gently on the cheek, specifically two centimeters in front of the ear, over the facial nerve (also known as CN VII). This test is used to check for hypocalcemia, a condition that can lead to tetany, which is the involuntary contraction of muscles. A twitch of the facial muscles in response to this tapping indicates a positive Chvostek’s sign. This is particularly relevant following a thyroidectomy, as the procedure can indirectly affect the parathyroid glands, potentially leading to hypocalcemia

Correct Answer is C
Explanation
The nurse should expect disequilibrium with movement if the client has impaired function of the vestibulocochlear nerve, as this nerve is responsible for hearing and balance. Deviation of the tongue from midline indicates impairment of the hypoglossal nerve (cranial nerve XII), loss of peripheral vision indicates impairment of the optic nerve (cranial nerve II), and inability to smell indicates impairment of the olfactory nerve (cranial nerve I).
Correct Answer is A
Explanation
An acute asthma attack is a sudden worsening of asthma symptoms, such as coughing, wheezing, tightness in the chest, and difficulty breathing. These symptoms happen because the airways in the lungs become narrow, irritated, swollen, and produce excess mucus.
An asthma attack can be triggered by various factors, such as allergic reactions, respiratory infections, tobacco smoke, cold air, and exercise. These triggers cause the immune system to react and release chemicals that cause inflammation and constriction of the airways.
Based on this information, the best answer to the question is a. Inability to exhale retained carbon dioxide. This is because during an asthma attack, the narrowed airways make it harder to exhale the air from the lungs, which leads to a buildup of carbon dioxide in the blood. This can worsen the symptoms and cause acidosis, a condition where the blood becomes too acidic.
The other options are not correct because:
b. Acute loss of alveolar elasticity is not a cause of asthma attacks, but a consequence of chronic obstructive pulmonary disease (COPD), a different lung condition that involves damage to the alveoli, the tiny air sacs in the lungs.
c. Decreased responsiveness of airways to allergens is not a cause of asthma attacks, but a goal of asthma treatment. Asthma medications aim to reduce the sensitivity and inflammation of the airways to prevent or reduce the frequency and severity of asthma attacks.
d. Suppressed bronchiolar inflammatory response is not a cause of asthma attacks, but a potential side effect of some asthma medications, such as corticosteroids. These drugs can suppress the immune system and increase the risk of infections in the airways.
