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?
- A. Kussmaul respirations
- B. Cheyne-Stokes respirations
- C. Biot's respirations
- D. Cluster breathing
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.

While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct Answer: B
Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.
A healthcare professional is preparing to draw a blood specimen from an adult client's central line. All of the following actions for this procedure are correct EXCEPT:
- A. Disconnect the current infusion
- B. Clean the cap with alcohol and attach a 5 cc syringe
- C. Draw 5 cc of a blood sample to discard
- D. Flush with saline after the sample
Correct Answer: B
Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.
A client is preparing to undergo a cystoscopy for stones. Which of the following statements indicates that the client understands the procedure?
- A. I better drink a lot of fluid now because I won't be able to after the test.
- B. I will probably see a little blood when I urinate.
- C. I will be able to go home after 3 days in the hospital.
- D. I won't need any pain medicine; this probably will not hurt.
Correct Answer: B
Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.
A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.
- A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
- B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
- C. The client should lie flat on their back for a specific period following the procedure.
- D. The risks of the procedure include headache, back pain, and infection.
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.
Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct Answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line.
Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
