1. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?
- A. Bounding erratic pulse.
- B. Regularly irregular pulse.
- C. Thready irregular pulse.
- D. No palpable pulse.
Correct answer: D
Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.
2. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?
- A. Administer the prescribed PRN lorazepam (Ativan).
- B. Start the prescribed PRN oxygen at 2 to 4 L/min.
- C. Administer the prescribed normal saline bolus and insulin.
- D. Encourage the patient to practice guided imagery for relaxation.
Correct answer: C
Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.
3. A client with a cold is taking the antitussive benzonatate (Tessalon). Which assessment data indicates to the nurse that the medication is effective?
- A. Reports reduced nasal discharge.
- B. Denies having coughing spells.
- C. Able to sleep through the night.
- D. Expectorating bronchial secretions.
Correct answer: B
Rationale: The correct answer is B. Denying having coughing spells indicates the effectiveness of benzonatate, an antitussive that suppresses coughing. The goal of antitussive medications like benzonatate is to reduce or eliminate coughing, so the absence of coughing spells signifies the drug's efficacy. The other options do not directly reflect the medication's intended effect and are not specific indicators of benzonatate's effectiveness.
4. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except
- A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
- B. Reinfection is rare despite adequate treatment
- C. Triple drug therapy has been shown to be more effective than dual drug therapy
- D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy
Correct answer: B
Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.
5. A client with a history of diabetes mellitus presents with confusion, sweating, and palpitations. What should the nurse do first?
- A. Check the client's blood glucose level.
- B. Administer 10 units of insulin.
- C. Give the client a high-protein snack.
- D. Measure the client's blood pressure.
Correct answer: A
Rationale: The correct first action for a client presenting with confusion, sweating, and palpitations, suggestive of hypoglycemia, is to check the client's blood glucose level. This step helps to confirm if the symptoms are due to low blood sugar levels and guides appropriate interventions. Administering insulin without knowing the current blood glucose level can be dangerous and is not recommended as the initial step. Offering a high-protein snack may be necessary after confirming hypoglycemia, but checking the blood glucose level takes precedence. Measuring blood pressure is not the priority in this situation; addressing hypoglycemia is the immediate concern.
