Nursing Elites

1. The healthcare provider formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely cause for this nursing diagnosis?

• A. Pain during coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct answer: B

Rationale: Clients with myasthenia gravis commonly experience muscle weakness, including in the muscles used for coughing. This diminished cough effort can lead to ineffective airway clearance, increasing the risk of respiratory complications. Therefore, the most likely cause for the nursing diagnosis 'High risk for ineffective airway clearance' in a client with myasthenia gravis is the diminished cough effort due to muscle weakness.

2. A 60-year-old man presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.

3. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

4. A client with a history of chronic alcohol use is admitted with confusion and an unsteady gait. Which deficiency should the nurse suspect?

• A. Thiamine (Vitamin B1)
• B. Cyanocobalamin (Vitamin B12)
• C. Folic acid
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Thiamine (Vitamin B1). Chronic alcohol use can lead to thiamine deficiency, which can result in neurological symptoms such as confusion and an unsteady gait. Thiamine is essential for proper brain function and nerve conduction, and its deficiency is common in individuals with alcohol use disorder. Cyanocobalamin (Vitamin B12) deficiency can also present with neurological symptoms, but in this case, the patient's history of chronic alcohol use points more towards thiamine deficiency. Folic acid deficiency typically presents with symptoms like fatigue and megaloblastic anemia. Vitamin D deficiency is associated with bone health issues rather than neurological symptoms.

5. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except

• A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
• B. Reinfection is rare despite adequate treatment
• C. Triple drug therapy has been shown to be more effective than dual drug therapy
• D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy

Correct answer: B

Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.
