1. An 85-year-old male has been losing mobility and gaining weight over the last two months. The patient also has the heater running in his house 24 hours a day, even on warm days. Which of the following tests is most likely to be performed?
- A. CBC (complete blood count)
- B. ECG (electrocardiogram)
- C. Thyroid function tests
- D. CT scan
Correct answer: C
Rationale: The symptoms of weight gain and poor temperature tolerance in an elderly male suggest a potential thyroid dysfunction. Thyroid function tests are crucial in differentiating between hyperthyroidism, hypothyroidism, and a euthyroid state. These tests involve measuring the serum levels of thyroid hormones T3 and T4, also known as thyroxine, to evaluate thyroid function accurately. A complete blood count (Choice A) would not directly address the symptoms presented. An electrocardiogram (Choice B) assesses heart activity and would not be the primary test for these symptoms. A CT scan (Choice D) provides detailed images of internal organs and structures, which would not be the initial investigation for the described symptoms.
2. A patient is admitted to the same-day surgery unit for a liver biopsy. Which of the following laboratory tests assesses coagulation? Select one that doesn't apply.
- A. Partial thromboplastin time
- B. Prothrombin time
- C. Platelet count
- D. Hemoglobin
Correct answer: D
Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.
3. A pregnant woman who is 36 weeks' pregnant and has hepatitis B is being informed by a nurse. Which of the following statements from the client indicates understanding of this condition?
- A. Now I know my baby will need a cesarean section.
- B. My baby will need two shots soon after birth.
- C. I will not be able to breastfeed.
- D. My baby's father does not need testing; I know I am the one with hepatitis.
Correct answer: B
Rationale: The correct answer is 'My baby will need two shots soon after birth.' A baby born to a mother with hepatitis B should receive two injections soon after birth to reduce the risk of contracting the disease. Within the first 12 hours post-birth, the baby should receive the first hepatitis B vaccine and hepatitis B immune globulin (HBIG) for additional protection. Option A is incorrect because the need for a cesarean section is not directly related to the mother's hepatitis B status. Option C is incorrect as breastfeeding can be safe if managed properly. Option D is incorrect as the baby's father should also be tested for hepatitis B to prevent transmission to the newborn.
4. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?
- A. Diarrhea
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.
5. While auscultating a patient's lungs, the nurse hears low-pitched, bubbling sounds during inhalation in the lower third of both lungs. How should the nurse document this finding?
- A. Inspiratory crackles at the bases
- B. Expiratory wheezes in both lungs
- C. Abnormal lung sounds in the apices of both lungs
- D. Pleural friction rub in the right and left lower lobes
Correct answer: A
Rationale: The correct answer is 'Inspiratory crackles at the bases.' Crackles are low-pitched, bubbling sounds typically heard during inspiration, which aligns with the nurse's finding. Expiratory wheezes are high-pitched sounds and are not consistent with the described auscultation findings. The lower third of both lungs refers to the bases, not the apices, so option C is incorrect. Pleural friction rubs are grating sounds heard during both inspiration and expiration, unlike the described finding of only hearing the sounds during inhalation in the lower third of both lungs.
