Free D444 Adult Health I Questions
A patient presents with muscle weakness and an ECG shows flattened T waves and prominent U waves. What condition might this patient be experiencing, and what immediate action should be taken?
-
Hyperkalemia; sodium levels should be monitored closely.
-
Normal electrolyte levels; no action is required.
-
Hypokalemia; potassium levels should be assessed and potassium replacement initiated.
-
Hypocalcemia; calcium supplementation should be given immediately.
Explanation
The ECG findings of flattened T waves and prominent U waves are characteristic of hypokalemia, a condition in which the serum potassium level is below normal. Potassium is vital for maintaining normal neuromuscular and cardiac function, and its deficiency can lead to muscle weakness, fatigue, and potentially life-threatening cardiac arrhythmias. The immediate nursing action involves assessing the patient’s potassium levels and initiating potassium replacement, either orally or intravenously depending on severity, while closely monitoring the patient’s cardiac rhythm and electrolyte status to prevent complications.
Why is it important to avoid constipation after a prostatectomy?
-
Constipation reduces the need for pain medication.
-
Constipation helps in faster recovery after surgery.
-
Constipation has no effect on post-operative pain.
-
Constipation increases abdominal and perineal pressure, leading to pain.
Explanation
After a prostatectomy, straining during bowel movements can increase intra-abdominal and perineal pressure, which can exacerbate pain, stress surgical sutures, and potentially lead to complications such as bleeding or wound dehiscence. Encouraging a high-fiber diet, adequate hydration, and sometimes stool softeners helps prevent constipation, reducing discomfort and promoting safe healing. Managing bowel habits is therefore a key component of post-operative care.
Which question has the most importance when the nurse admits a patient with a diagnosis of acute glomerulonephritis?
-
"Do you have a susceptibility to allergies?"
-
"Have you had any contact with anyone who has measles?"
-
"Have you recently had strep throat?"
-
"How much fluid do you drink in a day?"
Explanation
Acute glomerulonephritis is often post-infectious, most commonly following a streptococcal infection. Asking whether the patient has recently had strep throat is crucial because it can help identify the precipitating cause, guide treatment, and assist in monitoring for potential complications. While allergies, measles exposure, and fluid intake may provide useful background information, they are not directly related to the typical etiology of acute glomerulonephritis.
You are caring for an older adult in a nursing home. They start to become more confused than normal. Which of the following would you most likely suspect is the cause of this confusion?
-
chronic renal failure
-
glomerulonephritis
-
UTI
-
polycystic disease
Explanation
What is the primary purpose of thoracentesis?
-
To drain fluid from the pleural space
-
To perform a biopsy of lung tissue
-
To administer medication into the pleural cavity
-
To measure lung capacity
Explanation
Thoracentesis is a procedure performed to remove excess fluid from the pleural space, the area between the lungs and the chest wall. This procedure can serve both diagnostic and therapeutic purposes. Diagnostically, the collected fluid is analyzed to determine the cause of pleural effusion, such as infection, malignancy, or heart failure. Therapeutically, draining the fluid helps relieve symptoms like shortness of breath and chest pain caused by lung compression. It is not used to obtain lung tissue, administer medications, or measure lung capacity.
A patient presents with symptoms of fatigue and confusion, and lab results indicate a decreased pH and decreased HCO₃. Based on this information, what condition might the patient be experiencing?
-
Respiratory acidosis
-
Metabolic acidosis
-
Metabolic alkalosis
-
Respiratory alkalosis
Explanation
A decreased pH and decreased bicarbonate (HCO₃⁻) level indicate metabolic acidosis, a condition resulting from an excess of acid or a loss of base in the body. The fatigue and confusion are due to the acid-base imbalance affecting cellular metabolism and neurological function. Common causes include diabetic ketoacidosis, renal insufficiency, and prolonged diarrhea. The body attempts to compensate through hyperventilation (Kussmaul respirations), which helps expel CO₂ and partially correct the low pH.
What are the symptoms of hypoglycemia, and how should it be treated in a person with diabetes?
-
Symptoms include dizziness, fatigue, and shortness of breath, and it can be treated by consuming a high-protein snack, such as a protein bar or cheese and crackers
-
Symptoms include sweating, shakiness, confusion, and irritability, and it can be treated by consuming 15–20 grams of fast-acting carbohydrate, such as glucose tablets or fruit juice
-
Symptoms include abdominal pain, blurred vision, and chest pain, and it can be treated by taking a dose of insulin or an oral diabetes medication to raise blood sugar levels
-
Symptoms include nausea, headache, and rapid heartbeat, and it can be treated by consuming a slow-release carbohydrate, such as a granola bar or oatmeal
Explanation
Hypoglycemia occurs when blood glucose levels fall below normal, usually under 70 mg/dL. Typical symptoms include sweating, shakiness, confusion, irritability, dizziness, and hunger. In severe cases, it can cause seizures or loss of consciousness. The most effective immediate treatment is the administration of 15–20 grams of fast-acting carbohydrates, such as glucose tablets, fruit juice, or regular soda, to quickly raise blood glucose levels. After 15 minutes, blood sugar should be rechecked, and another serving of carbohydrates should be given if levels remain low.
A patient presents with clammy skin and confusion. Their blood sugar reading is 65 mg/dL. What is the most appropriate initial treatment?
-
Administer IV dextrose immediately.
-
Provide a high-protein snack.
-
Give juice or quick sugar.
-
Monitor the patient for further symptoms without treatment.
Explanation
A blood glucose level of 65 mg/dL indicates hypoglycemia, which can cause symptoms such as clammy skin, confusion, tremors, and weakness. The initial treatment for a conscious patient with mild to moderate hypoglycemia is to provide 15–20 grams of fast-acting carbohydrates, such as fruit juice, regular soda, or glucose tablets. This quickly raises blood sugar to a safe level. IV dextrose is reserved for severe hypoglycemia or when the patient is unconscious or unable to swallow safely. After stabilization, a more sustained carbohydrate source can be given to maintain normal glucose levels.
Interpret the mnemonic for lead placement in a 5-lead EKG and explain its significance in clinical practice.
-
The mnemonic assists in identifying patient symptoms related to hypocalcemia.
-
The mnemonic is used to remember the order of medications for cardiac patients.
-
The mnemonic is a guideline for assessing respiratory emergencies.
-
The mnemonic helps healthcare professionals accurately place EKG leads to ensure proper heart monitoring.
Explanation
The mnemonic for 5-lead EKG placement (e.g., “white on the right, smoke over fire on the left, green is the ground, brown in the center”) serves as a simple method to ensure accurate and consistent lead placement. Correct placement is crucial because it ensures the EKG accurately reflects the heart’s electrical activity, allowing healthcare providers to detect arrhythmias, ischemia, or other cardiac abnormalities. Improper lead placement can result in misinterpretation of the rhythm, potentially leading to incorrect treatment decisions.
What are signs and symptoms of hypoglycemia?
-
Cold and clammy- needs some candy
-
Headache, numbness, tingling
-
Lethargic, confusion
-
All of the above
Explanation
Hypoglycemia, or low blood glucose, can manifest through a range of symptoms that affect both the nervous and autonomic systems. Early signs include sweating, cold and clammy skin, shakiness, headache, and tingling sensations due to the body’s response to falling glucose levels. As hypoglycemia progresses, neurological symptoms such as lethargy, confusion, and even seizures may occur due to inadequate glucose supply to the brain. Recognizing all of these signs is crucial for timely intervention to prevent severe complications such as unconsciousness or hypoglycemic coma.
