1. A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?
- A. Elevated serum calcium
- B. Low serum parathyroid hormone (PTH)
- C. Elevated serum vitamin D
- D. Low urine calcium
Correct answer: A
Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.
2. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?
- A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
- B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
- C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
- D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%
Correct answer: D
Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.
3. A 4-year-old child with acute glomerulonephritis is admitted to the hospital. The nurse identifies which client problem in the plan of care as the priority?
- A. Infection related to hypertension
- B. Injury related to loss of blood in urine
- C. Excessive fluid volume related to decreased plasma filtration
- D. Retarded growth and development related to a chronic disease
Correct answer: C
Rationale: In acute glomerulonephritis, the child experiences excessive accumulation of water and retention of sodium, leading to circulatory congestion and edema. Excessive fluid volume is a primary concern due to the disease process. Hypertension and infection are not directly related to acute glomerulonephritis; therefore, they are not the priority client problems. While hematuria (blood in urine) may occur, it typically does not lead to significant injury that takes precedence over excessive fluid volume. Acute glomerulonephritis is an acute condition, not chronic; therefore, retarded growth and development related to a chronic disease is not the priority issue. With proper management, most children recover completely without long-term growth and development issues.
4. A client is brought into the emergency department after finishing a course of antibiotics for a urinary tract infection. The client is experiencing dyspnea, chest tightness, and agitation. Her blood pressure is 88/58, she has generalized hives over her body, and her lips and tongue are swollen. After the nurse calls for help, what is the next appropriate action?
- A. Start an IV and administer a 1-liter bolus of Lactated Ringer's solution
- B. Administer 0.3 mg of 1:1000 epinephrine IM
- C. Administer 15 mg diphenhydramine IM
- D. Monitor the client until help arrives
Correct answer: B
Rationale: A client experiencing an anaphylactic reaction will likely present with rash or hives, swelling of the lips, face, or tongue, hypotension, or dyspnea. In this scenario, the client is showing signs of anaphylaxis with dyspnea, chest tightness, hives, hypotension, and swelling of the lips and tongue. The next appropriate action would be to administer 0.3 mg of 1:1000 epinephrine intramuscularly. Epinephrine helps relax the muscles of the airway, improve breathing, and increase oxygenation, which is crucial in managing anaphylaxis. Starting an IV and administering fluids can be important but not the immediate priority. Diphenhydramine may be used as an adjunct therapy but should not delay the administration of epinephrine in the acute phase of anaphylaxis. Monitoring the client without providing immediate treatment can lead to a worsening of the anaphylactic reaction, potentially resulting in a life-threatening situation.
5. The healthcare provider assesses a patient suspected of having an asthma attack. Which of the following is a common clinical manifestation of this condition?
- A. Audible crackles and orthopnea
- B. An audible wheeze and use of accessory muscles
- C. Audible crackles and use of accessory muscles
- D. Audible wheeze and orthopnea
Correct answer: B
Rationale: Choice B, 'An audible wheeze and use of accessory muscles,' is the correct answer. In asthma, patients commonly present with wheezing due to airway constriction and the use of accessory muscles to aid in breathing. Audible crackles (rales) are more commonly associated with conditions like pneumonia, congestive heart failure, or pulmonary fibrosis. Orthopnea, which is difficulty breathing while lying flat, is typically seen in conditions like heart failure or chronic obstructive pulmonary disease, rather than asthma. Choice C is incorrect as crackles are not a typical finding in asthma. Choice D is incorrect as orthopnea is not a common clinical manifestation of asthma.
