Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?

Correct Answer: A

Rationale: Mr. N is exhibiting Kussmaul respirations, characterized by rapid, deep, and regular breathing. This type of respiratory pattern is commonly seen in metabolic acidosis, such as in diabetic ketoacidosis. Kussmaul respirations are a form of hyperventilation, leading to the elimination of carbon dioxide from the body. Choice B, Cheyne-Stokes respirations, is characterized by alternating periods of deep, rapid breathing followed by periods of apnea and is not typically associated with diabetic ketoacidosis. Choice C, Biot's respirations, involve irregular breathing patterns with periods of apnea and are not reflective of the described breathing pattern. Cluster breathing, as mentioned in Choice D, is not a recognized term in respiratory patterns and does not describe the breathing pattern observed in Mr. N.

Correct Answer: D

Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.

Correct Answer: D

Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.

Correct Answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

Correct Answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.
