The adrenal cortex is responsible for producing which substances?
- A. Glucocortocoids and androgens
- B. Mineralocortiroids and
- C. Catecholamines and epinephrine catecholamines
- D. Norepinephine and epinephrine
Correct Answer: A
Rationale: The correct answer is A: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with the outer layer responsible for producing mineralocorticoids like aldosterone, the middle layer producing glucocorticoids like cortisol, and the inner layer producing androgens. Glucocorticoids are essential for regulating metabolism and immune response, while androgens are male sex hormones. Choices B, C, and D are incorrect because mineralocorticoids, catecholamines, norepinephrine, and epinephrine are produced by different parts of the adrenal gland, not specifically by the adrenal cortex.

A client with suspected lymphoma is scheduled for lymphangiography. The nurse should inform the client that this procedure may cause which harmless, temporary change?
- A. Purplish stools
- B. Redness of the upper part of the feet
- C. Bluish urine
- D. Coldness of the soles
Correct Answer: B
Rationale: The correct answer is B: Redness of the upper part of the feet. During lymphangiography, a contrast dye is injected into the lymphatic vessels. This may cause temporary redness in the upper part of the feet due to the dye spreading throughout the lymphatic system. Purplish stools (A), bluish urine (C), and coldness of the soles (D) are not expected side effects of lymphangiography and do not have a direct correlation with the procedure.
The patient is having difficulty coping with her new diagnosis of lymphoma. Which response by the nurse is most helpful?
- A. “Don’t worry. You’ll be okay.”
- B. “The treatments you are receiving will make you feel better very soon.”
- C. “Who do you usually go to when you have a problem?”
- D. “Have you made end-of-life decisions?”
Correct Answer: C
Rationale: The correct answer is C because it helps the patient explore her support system. By asking who she usually goes to when facing problems, the nurse encourages the patient to identify her sources of emotional support, which can help her cope with the new diagnosis. This response acknowledges the patient's need for support and fosters a therapeutic relationship.
Explanation for incorrect choices:
A: "Don't worry. You'll be okay." - This response dismisses the patient's feelings and offers false reassurance, which may not address her emotional needs.
B: "The treatments you are receiving will make you feel better very soon." - While this statement provides information about treatment, it does not directly address the patient's difficulty in coping with the diagnosis.
D: "Have you made end-of-life decisions?" - This response may be premature and could unnecessarily increase the patient's anxiety about her prognosis.
While bathing an 82 y.o. man hospitalized with pneumonia, a nurse notes an ulcerated area on his penis. What action should the nurse take first?
- A. Report the ulcer to the admitting care provider.
- B. Teach the man about STD prevention.
- C. Ask the man if he has a history of syphilis.
- D. Clean the ulcer; reporting is not necessary because an STD is unlikely in a man this age.
Correct Answer: A
Rationale: The correct action is to report the ulcer to the admitting care provider first. This is essential because the ulcer could be a sign of an underlying infection or condition that needs immediate attention, especially in a hospitalized patient with pneumonia. Reporting the ulcer ensures prompt evaluation and appropriate treatment. The other options are incorrect because teaching about STD prevention and asking about syphilis assume the cause of the ulcer is related to a sexually transmitted infection, which may not be the case in this scenario. Additionally, cleaning the ulcer without proper assessment and diagnosis by a healthcare provider can lead to complications or delay in appropriate treatment.
Mrs. Zeno asks the nurse why the disease has occurred. The nurse bases the reply on the knowledge that there is:
- A. A genetic defect in the production of acetylcholine
- B. A reduced amount of neurotransmitter acetylcholine
- C. A decreased number of functioning acetyl-choline receptor sites
- D. An inhibition of the enzyme Ache leaving the end plates folded.
Correct Answer: C
Rationale: The correct answer is C: A decreased number of functioning acetyl-choline receptor sites. This is because in diseases like myasthenia gravis, there is an autoimmune attack on acetylcholine receptor sites, leading to decreased functionality. Choice A is incorrect because it refers to a genetic defect in acetylcholine production, which is not typically the cause of myasthenia gravis. Choice B is incorrect as it suggests a reduced amount of acetylcholine, which is not the primary issue in myasthenia gravis. Choice D is incorrect as it mentions inhibition of the enzyme Ache, which is not the main mechanism in this disease.
Which action indicates the nurse is using a PICOT question to improve care for a patient?
- A. Practices nursing based on the evidence presented in court
- B. Implements interventions based on scientific research
- C. Uses standardized care plans for all patients. NursingStoreRN
- D. Plans care based on tradition
Correct Answer: B
Rationale: The correct answer is B because using a PICOT question involves formulating a research question to guide evidence-based practice. B indicates the nurse is implementing interventions based on scientific research, aligning with the PICOT framework (Patient, Intervention, Comparison, Outcome, Timeframe). This approach ensures that care decisions are supported by the best available evidence, leading to improved patient outcomes.
Choice A is incorrect because practicing nursing based on court evidence does not align with the PICOT framework. Choice C is incorrect as using standardized care plans for all patients may not consider individual patient needs and preferences as required in a PICOT question. Choice D is incorrect as planning care based on tradition does not involve integrating current research evidence as in the PICOT approach.
