HESI Medical Surgical Practice Quiz
1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:
- A. Compensated metabolic acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic alkalosis
- D. Uncompensated respiratory acidosis
Correct answer: B
Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.
2. The healthcare provider prescribes terbutaline (Brethine) for a client in preterm labor. Before initiating this prescription, it is most important for the LPN/LVN to assess the client for which condition?
- A. Gestational diabetes.
- B. Elevated blood pressure.
- C. Urinary tract infection.
- D. Swelling in lower extremities.
Correct answer: A
Rationale: The correct answer is A: Gestational diabetes. Terbutaline (Brethine) is known to cause hyperglycemia, so it is crucial to assess for gestational diabetes before administering it. Assessing for elevated blood pressure (choice B), urinary tract infection (choice C), or swelling in lower extremities (choice D) is not directly related to the potential side effect of terbutaline in causing hyperglycemia.
3. What type of tissue lines the testes?
- A. Glandular tissue.
- B. Squamous epithelium.
- C. Transitional epithelium.
- D. Stratified epithelium.
Correct answer: A
Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.
4. Urinary catheterization is prescribed for a postoperative female client who has been unable to void for 8 hours. The nurse inserts the catheter, but no urine is seen in the tubing. Which action will the nurse take next?
- A. Clamp the catheter and recheck it in 60 minutes.
- B. Pull the catheter back 3 inches and redirect it upward.
- C. Leave the catheter in place and reattempt with another catheter.
- D. Notify the healthcare provider of a possible obstruction.
Correct answer: C
Rationale: In this scenario, if no urine is seen in the tubing after inserting the catheter, it is likely that the catheter is in the vagina rather than the bladder. Leaving the first catheter in place will help locate the meatus more easily when attempting the second catheterization. This approach ensures correct placement of the catheter in the bladder and minimizes the risk of causing unnecessary discomfort or trauma to the patient.
5. A 7-year-old child is admitted to the hospital with nephrotic syndrome. The nurse notes that the child has gained 3 pounds in the past 24 hours. What should the nurse do first?
- A. Administer a diuretic as prescribed
- B. Restrict the child’s fluid intake
- C. Notify the healthcare provider
- D. Measure the child’s abdominal girth
Correct answer: C
Rationale: In a child with nephrotic syndrome experiencing sudden weight gain, the priority action for the nurse is to notify the healthcare provider. This weight gain could indicate worsening edema or fluid retention, necessitating immediate medical evaluation and intervention. The healthcare provider can conduct a comprehensive assessment, order necessary tests, and adjust the treatment plan accordingly. Administering a diuretic, restricting fluid intake, or measuring abdominal girth should not be initiated without healthcare provider consultation to ensure appropriate management of the child's condition.
