A nurse is reviewing the medical history of a client who has myasthenia gravis and is asking about starting neostigmine. The nurse should identify which of the following client conditions as a potential contraindication for cholinesterase inhibitor therapy?
Cataracts
Hypertension
Hypothyroidism
Peptic ulcer disease
The Correct Answer is D
Rationale:
A. Cataracts are not a contraindication for cholinesterase inhibitors like neostigmine.
B. Hypertension is not a direct contraindication for cholinesterase inhibitor therapy, although caution may be exercised depending on the overall health status of the client.
C. Hypothyroidism is not contraindicated for cholinesterase inhibitors; however, it should be managed appropriately.
D. Peptic ulcer disease is a significant contraindication for cholinesterase inhibitors like neostigmine because these medications can increase gastric secretions and motility, potentially exacerbating ulcer conditions and leading to complications.

Correct Answer is ["A","D"]
Explanation
Rationale:
A. Terazosin is indicated for the treatment of hypertension as it works by relaxing blood vessels, leading to lower blood pressure.
B. Terazosin is not indicated for heart failure; other medications are typically used to manage this condition.
C. Male pattern baldness is treated with other medications, such as finasteride, rather than terazosin.
D. Terazosin is also indicated for benign prostatic hypertrophy (BPH), as it helps alleviate urinary symptoms associated with this condition by relaxing the smooth muscles in the prostate and bladder neck.
E. Terazosin is not indicated for erectile dysfunction; it is primarily used for hypertension and BPH.
Correct Answer is B
Explanation
Rationale:
A. Diazepam is a benzodiazepine used for anxiety and sedation but is not effective for treating malignant hyperthermia.
B. Dantrolene is the specific antidote for malignant hyperthermia, and the nurse should expect to administer it to help reduce the severe muscle contractions and hypermetabolism associated with this condition.
C. Cyclobenzaprine is a muscle relaxant used for muscle spasms but is not indicated for malignant hyperthermia.
D. Metaxalone is also a muscle relaxant, but like cyclobenzaprine, it is not effective for managing malignant hyperthermia and would not be used in this situation.
